  • my json parser works fine.. details
  • @ErikE Valid JSON is any "*value*" [defined in the spec]( URL_http://json.org /) -- that's not just "*object*.. details
  • In fact, a CODETERM9 is _specifically_ used to represent a name/value pair object.. details
  • CODETERM10 can potentially return _any_ of the aforementioned value types, that's why it needs to fall back to the greatest common denominator type: CODETERM11 (and _not_ CODETERM12 ).. details
  • It's _your responsibility_ to ensure that you're casting to the correct type using your knowledge of the incoming data structure.. details
  • Instead, retrieve the value, create a CODETERM5 from it and add it to the CODETERM6 .. details
  • _If the value is not a string and is not null, then it is converted to a string._** So, it converts CODETERM1 with CODETERM2 .. details
  • Great... so did you use this suggested function?. details

  • For example, in your case, you may create a JSONObject like the following and invoke its toString() function.. details
  • This can safe your time from formatting string to fit the JSON format: CODESNIPPET_JAVA2 .. details
  • Not sure what exact task you're working, but there are many JSON libraries for Java which can do this for you such as URL_http://json.org/java/ [json-in- java] and URL_https://code.google.com/p/google-gson/ [google-gson] .. details
  • For example, in json in java, once you have filled all the values in its URL_http://www.json.org/javadoc/org/json/JSONObject.html [JSONObject] , then converting it into JSON string is fairly easy: CODESNIPPET_JAVA1 .. details
  • Using the org.json library, you can chain together your get methods, like so: CODESNIPPET_JAVA1 .. details
  • Using the typed getMethods and chaining as I demonstrated here also helps clean up the code a lot!. details
  • if it is a JSONObject, the parameter you pass to the get method is the key; if it is a JSONArray, you pass in the index!. details
  • Android comes with the org.json library built in!!. details
  • Json Objects are basically just big nested sets of arrays and key-value pairs.. details
  • Hope it helps!. details
  • You must surround the string value with double quotes.. details
  • Once converted, you can use URL_http://www.json.org/javadoc/org/json/JSONObjec t.html#append%28java.lang.String,%20java.lang.Object%29 [JSONObject.append()] to append the key "age" with value "21" to it.. details
  • It's worth keeping in mind that Java's Serializable is just one implementation of serializing objects.. details
  • URL_http://json.org/ [JSON-docs] says An object is an unordered set of name/value pairs So the way is getting the values in required order,rather than ordering CODETERM1 .. details
  • YOu can have a look to the library below: URL_https://github.com/douglascrockford/JSON-java [json-java] You can use the URL_http://www.json.org/javadoc/org/json/JSONObject.html [JSONObject] to parse a String representing a JSON object and then extract the values you are interested in.. details
  • If the value of the "datasets" attribute is an associative array rather than a plain array, you will get a CODETERM1 .. details
  • something like size() etc.,?. details
  • Also, you might find URL_http://viralpatel.net/blogs/creating-parsing-json- data-with-java-servlet-struts-jsp-json/ [this] examples useful when manually creating/parsing JSON data.. details
  • I suggest you to take a brief look at URL_http://www.json.org/ [json.org] in order to understand JSON syntax, which is pretty simple... Basically these are the possible JSON elements: CODESNIPPET_JAVA3 .. details
  • In addition, here is a JSON validation tool to quickly debug / correct JSON syntax CODESNIPPET_JAVA7 .. details
  • Here is some explaination on what is going on with your JSON data.Currently it looks like : CODESNIPPET_JAVA4 .. details
  • Is not going to work because there is no object inside this JSON data called "Categories", instead it has a String element with value "Categories".. details
  • URL_http://www.json.org/javadoc/org/json/JSONArray.html This question probably wouldn't have been asked if there was a simple toArray().. details
  • See details from the URL_http://www.json.org/ [JSON-specification] : _Definition of an object_: An object is an unordered set of name/value pairs.. details
  • Each name is followed by : (colon) and the name/value pairs are separated by , (comma).. details
  • _Definition of an array_: An array is an ordered collection of values.. details
  • Values are separated by , (comma).. details
  • A correct representation would look like this: CODESNIPPET_JAVA2 .. details
  • What I chose to do is modify the public domain JSON.org library to support shell comments and adding comments to the JSON object, as I've done in this GitHub gist: URL_https://gist.github.com/peteroupc/5529464 [ URL_https://gist.github.com/peteroupc/5529464 ] Example of use: CODESNIPPET_JAVA1 .. details
  • Fortunately, a specification called JSON Pointer was recently publishedas RFC 6901.. details
  • I've tried pulling the first element from the array and getting its type, in hopes of creating an array instance of that type, like so: CODESNIPPET_JAVA1 .. details
  • There are micro-optimisations you can make, like data.ensureCapacity(stream.available()) and making your chunks 8K or 64K, etc, but really what would be better would be to serialise your data or save it to an SQL table after parsing, then use that except if you detect that the JSON file has been updated.. details
  • It's good practice to create a model class containing the CODETERM13 's elements as member variables and providing a Constructor that takes the CODETERM14 containing the objects data values.. details
  • If you want to parse the elements (more CODETERM5 s) within the CODETERM6 you can do so by using the classes provided by the URL_https://developer.android.com/reference/org/json/package-summary.html [org.json] package that is being distributed with Android or use another JSON library like URL_https://code.google.com/p/google-gson [GSON] or URL_http://jackson.codehaus.org [Jackson] .. details
  • From within this Constructor you can then read the values of the JSONObject like this: CODETERM15 For starters you can go with the org.json package and get familiar with URL_http://www.json.org [JSON] itself.. details
  • The resulting value will be of the type CODETERM9 .. details
  • For the JSON could you use Google Gson ( URL_https://code.google.com/p/google- gson/ [ URL_https://code.google.com/p/google-gson/ ] ) is a very useful and easy library convert JSON-JAVA and vice-versa.. details
  • Thanks, this is the solution!. details
  • In the simplest way, you could use the library available at URL_http://json.org [json.org] for java (download URL_http://www.json.org/java/index.html [here] ) and use a code similar to: CODESNIPPET_JAVA1 .. details
  • For basic authentication you could use something like: Authenticator.setDefault(new Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication ("usr", "pass".toCharArray()); }}); Something related URL_http://stackoverflow.com/q/496651/1001027 [here] and URL_http://docs.oracle.com/javase/6/docs/technotes/guides/net/http-auth.html [documentation] .. details
  • For basic authentication you could use something like: Authenticator.setDefault(new Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication ("usr", "pass".toCharArray()); }}); Something related URL_http://stackoverflow.com/q/496651/1001027 [here] and URL_http://docs.oracle.com/javase/6/docs/technotes/guides/net/http-auth.html [documentation] .. details
  • I recommend using JSON:On the server side, use one of the JSON libraries listed on URL_http://www.json.org [ URL_http://www.json.org ] .. details
  • You could also use $.get if that works for you .. details
  • Pretty simple.. details
  • The best solution is to use URL_http://www.json.org/javadoc/org/json/JSONObjec t.html#get%28java.lang.String%29 [CODETERM1] and check for the type using CODETERM2 operator.. details
  • Thanks veer.. details
  • @Squonk ah, thanks - so much for that idea.... details
  • @Squonk ah, thanks - so much for that idea.... details
  • Too fast :( raaa.. details
  • Make sure you define all constructors on your subclasses and call their super() counterparts as well as implement specific methods that return the parent types such as getJSONObject() and getJSONArray() from properties.. details
  • Since you mentioned optimizations :), if val1 is null you will get a NullPointerException from this code if (!val1.equals(val2)) {.. details
  • Since you mentioned optimizations :), if val1 is null you will get a NullPointerException from this code if (!val1.equals(val2)) {.. details
  • In other words, I want all the lists, as well as each CODETERM2 , to be "named".. details
  • In my code, I am trying to convert a CODETERM1 into JSON using the URL_http://json.org/java/ [Java-JSON] library (however I'd also accept any answer using GSON as well).. details
  • Thanks in advance!. details
  • _As a consequence, JSON libraries are free to rearrange the order of the elements as they see fit.. details
  • _As a consequence, JSON libraries are free to rearrange the order of the elements as they see fit.. details
  • This is not a bug._**Just curious to know, what is be the benefit in re-arranging elements.Thanks,durai.. details
  • Bear in mind that there are several ways to serialize RDF triples, RDF/Turtle is the most readable.. details
  • You might need to have a look at the Turtle spec document to understand how this gets build, it is kind of intuitive anyway.. details
  • If you're using the URL_http://www.json.org/java/index.html [JSON.org-Java- implementation] , which is open source, you can just make JSONArray implement the CODETERM1 interface and add the following method to the class: CODESNIPPET_JAVA1 .. details
  • All this works because the JSONArray class is backed by a simple ArrayList, which is already iterable.. details
  • To achieve CDATA structure you can apply custom logic to handle string based values (and do it in the same way both for .net and java implementations).. details
  • In using JSONArray , I have to declare a JSONObject?How can I extract the values from this.the values of latitude and longitude.. details
  • The json.org library is very simple and might be good enough.. details
  • You can use a library like from URL_http://www.json.org/java/index.html [ URL_http://www.json.org/java/index.html ] or URL_http://jackson.codehaus.org/ [ URL_http://jackson.codehaus.org/ ] or you can try to do it manually.. details
  • Then I noticed that even when reading JSON responses from the URL_http://cloudbase.io [ URL_http://cloudbase.io ] APIs I transform the string successfully to a JSONOjbect.. details
  • I tried to log the toString() of the JSONObject inserted under the "$group" key and it looks correct CODESNIPPET_JAVA2 .. details
  • +1 for a good and simple answer, keep it up... ;).. details
  • Thanks so much for the info.. details
  • Thanks so much for the info.. details
  • Thanks for the detailed answer.. details
  • Works like a charm, but I am unsure if it's the best way.. details
  • But it can be used for JSON as well, look here URL_http://xstream.codehaus.org /json-tutorial.html [XStream-JSON-Tutorial] More libraries can be found here URL_http://www.json.org/ [ URL_http://www.json.org/ ] EDIT For displaying in HTML you can use Javascript: URL_http://msdn.microsoft.com /en-us/library/ie/cc836459%28v=vs.94%29.aspx [JSON.stringify- Function-(JavaScript)] CODESNIPPET_JAVA1 .. details
  • Note: Remember, I would prefer to not use other libraries to do this.. details
  • I'm pretty sure it's not best practices to depend on exceptions thrown as part of logic in a method.. details
  • My Question:** How can I improve these methods to check that a string is valid json without having to ignore CODETERM1 s by using the URL_http://json.org/java/ [official-JSON-for-java-library] ?. details
  • From URL_http://json.org/ [json.org] : !. details
  • The JSON.org API is intended for very simple serialization/deserialization, it can't do what your looking for.. details
  • there are many simple libraries to deal with JSON in java, check: URL_http://www.json.org/ [JSON] there is no built in support in Java .. details
  • Use org.json.JSONObject URL_http://www.json.org/javadoc/org/json/JSONObject.html [ URL_http://www.json.org/javadoc/org/json/JSONObject.html ] You can create a JSON object and then use the put method to add your values.. details
  • Hm... To specify, you mean something like that: new JSONObject(fmList, new String[] { "items", "dirs", "files", ... }).toString()?. details
  • JSON is used to exchange data what you are trying to do is exchange JS which is not what it's intended for, nor is it safe to do so.. details
  • I'm curious to see what your JS is going to look like given you have JS in your JSON.. details
  • I did a pretty extensive evaluation of json-java libraries a few months ago, and chose json-smart: URL_http://code.google.com/p/json-smart/ [ URL_http://code.google.com/p/json-smart/ ] Has been working well.. details
  • Thanks for distinction!.. details
  • edit This has the advantage that you can build your responses in different layers and return them as an object .. details
  • You could use a package like org.json URL_http://www.json.org/java/ [ URL_http://www.json.org/java/ ] Because you will need to use JSONObjects more often.. details
  • Take a look at the JSONObject reference: URL_http://www.json.org/javadoc/org/json/JSONObject.html [ URL_http://www.json.org/javadoc/org/json/JSONObject.html ] Without actually using the object, it looks like using either getNames() or keys() which returns an Iterator is the way to go.. details
  • A really useful response, thanks Greg!.. details
  • Here is a simple one from json.org where you find lots of other alternatives.. details
  • Values are separated by , (comma).. details
  • Each one of these two Objects conssits of various name/value pairs.. details
  • The name/value pair CODETERM6 is just one of these.. details
  • Regarding the basic JSON concepts, see URL_http://json.org/ [ URL_http://json.org/ ] : Object: An object is an unordered set of name/value pairs.. details
  • Perhaps you can see that you have one JSON Object with four name/value pairs: CODETERM1 CODETERM2 CODETERM3 CODETERM4 The last three of these have simple numeric values while the first ( CODETERM5 ) is an Array of two more Objects**.. details
  • Array: An array is an ordered collection of values.. details
  • Edit: There is not much you can do to simlify the JSON from your question except pretty-print it: CODESNIPPET_JAVA1 .. details
  • A string is very much like a C or Java string.. details
  • Each name is followed by : (colon) and the name/value pairs are separated by , (comma).. details
  • Number: A number is very much like a C or Java number, except that the octal and hexadecimal formats are not used.. details
  • convert string->jsonobject->jsonarray->get value .. details
  • ...which results in CODETERM5 , which you can use like this in your Java code: CODESNIPPET_JAVA5 .. details
  • Changing the JSON data As simple as adding a CODETERM10 at the beginning and CODETERM11 at the end: CODESNIPPET_JAVA4 .. details
  • Since your JSON data looks more like an CODETERM6 than an CODETERM7 maybe you should try using URL_http://www.json.org/javadoc/org/json/JSONObject.html [CODETERM8] instead.. details
  • I did figure out how to accomplish my task of taking a JSONArray and alphabetizing by "name" element.. details
  • Thanks.. details
  • Well that explains it.. details
  • Thanks.. details
  • Search for JSONArray and JSONObject URL_http://www.json.org/javadoc/org/json/JSONArray.html [ URL_http://www.json.org/javadoc/org/json/JSONArray.html ] it's pretty easy to work with them.. details
  • Using the JSONObject class from org.json, I could go down the road of doing something like this: CODESNIPPET_JAVA4 .. details
  • In addition to all of this, I'm dealing with many providers for animal objects and I'll eventually be looking to have some succinct configuration format for describing the transformations (like, maybe, CODETERM1 ).. details
  • A bit more information would really be helpful.. details
  • JSON notation doesn't support anything but strings for map keys (as specified URL_http://json.org/ [here] ).. details
  • CODETERM1 -- the one from json.org, is the simplest API to use to parse JSON.. details
  • I find that the built-in JSON parser (org.json) parses the file very slowly, however once it's parsed, I can access and manipulate the data very quickly.. details
  • where readFileToMemory(String) looks like this: CODESNIPPET_JAVA2 .. details
  • To do so, I recommend checking out the simple Java library at URL_http://www.json.org/java/index.html [ URL_http://www.json.org/java/index.html ] Once you've generated your JSON, you can use something like the code below to POST it CODESNIPPET_JAVA1 .. details
  • I'd recommend using a JSon framework in Java, such as URL_http://www.json.org/java/ [these-examples] .. details
  • Here is the fully working and tested corrected code: CODESNIPPET_JAVA2 .. details
  • Java supports JSON objects: URL_http://www.json.org/java/ [ URL_http://www.json.org/java/ ] Use these methods.. details
  • Then run a script to fill the value of the input with jsonText and submit it.. details
  • You could serialize it to URL_http://json.org/ [JSON] so it looks something like this: CODESNIPPET_JAVA1 .. details
  • Thank you.. details
  • Each name is followed by : (colon) and the name/value pairs are separated by , (comma).. details
  • Object declaration syntax according URL_http://json.org/ [specification] : An object is an unordered set of name/value pairs.. details
  • After that you can work with CODETERM8 like any other CODETERM9 .. details
  • Assuming the structure you posted, you'd need to do something like this: CODESNIPPET_JAVA1 .. details
  • This works just great!.. details
  • This works just great!.. details
  • Thanks a lot for the quick an exhaustive answer !. details
  • The answer is to use a URL_http://json.org/javadoc/org/json/JSONArray.html [JSONArray] as well, and to dive "deep" into the tree structure: CODESNIPPET_JAVA1 .. details
  • Does it support fluent syntax?. details
  • thanks for your reply but my jsonlib-2.2.3.jar doesn't have isNull method declaration in it.. details
  • Happy coding and -- good luck :) In Java one [untested] approach might be to use a regular expression (via CODETERM12 ): CODESNIPPET_JAVA1 .. details
  • Ive tried many different methods of reading the data in but ive had no luck.. details
  • commons.io library from apache is a great way to do this.. details
  • These two characters are your ASCII hex values.. details
  • Once you do this, read the char array in a for loop looking for "\", if you have a hit then look for "x" in the next array position.. details
  • Using Html.fromHtml() Took care of this.. details
  • Using Html.fromHtml() Took care of this.. details
  • It should be noted that this is not "JSON date format" -- the [JSON standard]( URL_http://www.json.org /) does not include a date format.. details
  • The org.json project created a generic URL_http://www.json.org/javadoc/org/json/JSONObject.html [JSONObject] class, which represents a single, generic key/value pair in a larger JSON representation.. details
  • If you don't have all of the data and cannot instantiate the object, then you'll either need to pass empty values (which should signal a red flag to you) or fetch that data from the datastore first.. details
  • Though in this particular case this library is more then enough.. details
  • URL_https://github.com/douglascrockford/JSON-java [The-CODETERM9-and- CODETERM10-classes-are-taken-from-here] URL_http://mvnrepository.com/artifact/org.json/json/20090211 [The-jar-for-the- library-is-availalbe-here] You could use CODETERM11 if you like.. details
  • I personally use CODETERM12 if I have a bean object for a corresponding CODETERM13 String, otherwise CODETERM14 is more than enough.. details
  • An almost 10x performance difference!. details
  • UPDATE2 Here's a very simple test case that illustrates the poor performance relative to org.json: CODESNIPPET_JAVA5 .. details
  • UPDATE2 Here's a very simple test case that illustrates the poor performance relative to org.json: CODESNIPPET_JAVA5 .. details
  • For field access like you are using (not get/set methods) you have to specify them: URL_http://www.json.org/javadoc/org/json/JSONObject.html#JSONObject%28ja va.lang.Object,%20java.lang.String%5B%5D%29 [ URL_http://www.json.org/javadoc/org/j son/JSONObject.html#JSONObject(java.lang.Object,-java.lang.String[])] You either use the JSON Writer or "Stringer" (write to stream or create String) to not get a pretty printed json.. details
  • URL_http://www.json.org/javadoc/org/json/JSONWriter.html [ URL_http://www.json.org/javadoc/org/json/JSONWriter.html ] URL_http://www.json.org/javadoc/org/json/JSONStringer.html [ URL_http://www.json.org/javadoc/org/json/JSONStringer.html ] Update: Also the class can't be private with the simple org.json lib.This works fine: CODESNIPPET_JAVA1 .. details
  • I have two simple Java classes: CODESNIPPET_JAVA1 .. details
  • I've tried to find any useful example to solve this easy task, however, nothing really helpful was found.. details
  • _What is the right way to serialize this simple object to JSON string using classes from CODETERM5 package?_ Thank you for help!. details
  • The Java library from JSON.org is just that, a huge library that requires countless classes and packages to do something relatively simple.. details
  • You can call URL_http://www.json.org/javadoc/org/json/JSONObject.html#names%28%29 [CODETERM1] on a CODETERM2 to get a CODETERM3 of the names of its elements - this would let you do logic on them or retrieve their corresponding values dynamically.. details
  • Thanks.. details
  • jsonarr.add(1,""); is working fine.. details
  • +1 json.org - simple and sufficient in most cases (added the link to json.org on your answer - hope you dont mind).. details

  • You just grab json, pass the class to want to deserialize into, and your class attributes will be matched to the JSON, but then again, everyone has their own requirements, maybe you can't afford the luxury to have pre-mapped classes on the deserializing side because things might be too dynamic on the JSON Generating side.. details
  • The reverse process is fairly simple, I mean converting a string to json object/array.. details
  • In order to be correctly parsed you just have to know if you are parsing an array or an object.. details

  • It parses/writes JSON, and offers a simple node-based API.. details
  • Beside this I would like to mention my humble opinion on your decision to go ahead with Android native application and WCF Json services.. details
  • Android has JSON parsers build in its SDK - the package is org.json Beside this you can use libraries like Gson that wraps the json parsing in simple to use API.. details

  • Doing so creates a great deal of extra padding around the actual data no matter which DTD is used.. details
  • In comparison, the serialization of data using JSON by the sender is relatively quick and compact because the structure of JSON reflects the structure of standard programming data types and the encoding mechanism adds only the minimum number of characters required to indicate the structure and value of the data.. details

Summaries of the opinions about org.json using three algorithms (Textrank, Lexrank and Luhn) adopted from extractive summarization. Each algorithm was used once for the positive opinions and once for the negative opinions.
  • , which you can use like this in your Java code: CODESNIPPET JAVA5 .
  • If you want to parse the elements (more JSONObject s) within the JSONArray you can do so by using the classes provided by the org json package that is being distributed with Android or use another JSON library like GSON or Jackson .
  • You can create a JSONObject , and then convert it to XML using the XML class in the org json namespace Wrapping the json string in the object is as easy as passing it in its constructor CODESNIPPET JAVA1 .
  • If your JSON data does not follow a specific structure, don't use GSON, but a regular JSON library (like the one from json org ) that will give you an instance of a class like JSONObject , from which you can access data like jsonObject.getString("key") .
  • YOu can have a look to the library below: json java You can use the JSONObject to parse a String representing a JSON object and then extract the values you are interested in .
  • JSONObject (from org json) is one of the simple JSON libraries that you can use .
  • Thanks for that but I would prefer to not use any plugs in, I know there is a simple way that I could do it with a simple for each object in the array loop I had it going before but I cant find it again .
  • You can use a library like JSON java CODESNIPPET JAVA1 .
  • From json org : !.
  • i like this from ** and JSONArray .
  • The best way if obviously to take this to whatever is outside your control and tell them to fix it : ) Workarounds One way to work around it is to create a servlet filter that removes all characters that are incompatible with both UTF 8 and ISO 8859 1 and replace them with JSON escapes: In the following fragment, replace '' with '\u00E9' so that any offending ISO 8859 1 character is safely transported in the 7 bits that are identical: Before: GET After: jQuery.ajax It's not as legible, but semantically speaking, it's the same, and any good JSON library should treat them identically .

  • You just grab json, pass the class to want to deserialize into, and your class attributes will be matched to the JSON, but then again, everyone has their own requirements, maybe you can't afford the luxury to have pre mapped classes on the deserializing side because things might be too dynamic on the JSON Generating side .
  • : So I understand that you can convert JSON strings to strings and handle JSON objects in general through the org json bundle in Android, but here's my current situation: I need to take a JSON string from a certain URL (I'm already able to successfully do this) and make it into an array .
  • To learn more about JSON, be sure to read the JSON Wikipedia entry and to visit the official JSON page (which also gives you a Java implementation of the JSON data interchange format , though maybe not the most efficient one for processing a lot of data) .
  • If you're using the JSON org Java implementation , which is open source, you can just make JSONArray implement the [{json object},{json object},{json object}] interface and add the following method to the class: CODESNIPPET JAVA1 .
  • Json is so easy with Jquery One of the best texts I've found about Json Because JSON was designed for the purpose of serializing and unserializing data being sent to and from JavaScript applications, the advantages of using JSON relate to the advantages of JSON over other means of serialization .
  • In comparison, the serialization of data using JSON by the sender is relatively quick and compact because the structure of JSON reflects the structure of standard programming data types and the encoding mechanism adds only the minimum number of characters required to indicate the structure and value of the data .
  • you basically use certain classes in java like the ones defined here: convert the final output to a json string and then send it to javascript there you convert the json string back to json using eval or probably using a library called json2 js and you are all set here is code for the same: CODESNIPPET JAVA1 .
  • The best way if obviously to take this to whatever is outside your control and tell them to fix it : ) Workarounds One way to work around it is to create a servlet filter that removes all characters that are incompatible with both UTF 8 and ISO 8859 1 and replace them with JSON escapes: In the following fragment, replace '' with '\u00E9' so that any offending ISO 8859 1 character is safely transported in the 7 bits that are identical: Before: GET After: jQuery.ajax It's not as legible, but semantically speaking, it's the same, and any good JSON library should treat them identically .

  • For field access like you are using (not get set methods) you have to specify them: va lang Object,%20java lang String%5B%5D%29 son JSONObject html#JSONObject(java lang Object, java lang String) You either use the JSON Writer or "Stringer" (write to stream or create String) to not get a pretty printed json .
  • Thanks for that but I would prefer to not use any plugs in, I know there is a simple way that I could do it with a simple for each object in the array loop I had it going before but I cant find it again .
  • There are micro optimisations you can make, like data ensureCapacity(stream available()) and making your chunks 8K or 64K, etc, but really what would be better would be to serialise your data or save it to an SQL table after parsing, then use that except if you detect that the JSON file has been updated .
  • It dounds like it should be something like: List<List<list<String>>> It's a bit more manual but have a look here: This will give you a JSONObject that is much easier to use than parsing the string yourself, but you will still have to drill into it and manually build your map .
  • I don't have the json commands at compile time but do know that these commands will always end in a printjson EDIT ** So to simplify, for example, I am looking for a way to parse the following output into Java Objects (The individual key value pairs are not known at compile time) CODESNIPPET JAVA1 .

  • Here is the error I get .
  • There are other similarly simple to use libraries (Gson was already mentioned); but some choices are more laborious, like original org json library, which requires you to create intermediate "JSONObject" even if you have no need for those .
  • It provides various libraries which can be used with Java, I've personally used this one, JSON lib which is an implementation of the work in the site, so it has exactly the same class methods etc in this page .
  • The problem: If I use this code: CODESNIPPET JAVA4 .
  • The only problem with JSON in Java is that if your XML has a single child, but is an array, it will convert it to an object instead of an array .
  • The problem is when I get a response from a WebService It is of the org json JSONArray class .
  • If you are having problems using one of the json libraries post up the code your trying to use and we will help you out .

  • Refer to the JSON syntax diagrams at The fact that the double backslashes are giving you problems actually means that the software that is reading the files is broken .
  • However I don't like the cast there, is there the possibility for a org.json ?Is there a method equivalent to JsonNode in JSONException so that I have proper error handling in case it isn't an array?.

  • The biggest drawback with the built in org json package for android runtime 3 was 1 the JSONTokener constructor only accepts a String, no Reader 2 the lack of practical support for pull parsing This typically means you need to keep the whole file in memory (think 2x byte size) and in addition hold all the resulting JSON objects in memory at the same time, before you start making your data binding .
  • Therefore, you might want to file a bug with them, or use the other fromObject signature (which lets you pass in a config argument; I didn't look at that Config extensively, but based on a quick look it seemed like it could solve this problem) .

Object:
  • I am a beginner on JSON in Java URL_http://json.org/java/ [ URL_http://json.org/java/ ] How can I create a JSON object like this?
  • N/A
Features:
  • Are you trying to populate a custom Java data structure, or do you just want to quickly retrieve one or two values from the JSON and move on?
  • Maybe I wasn't clear in my question.
Portability:
  • I am working on Java and Android.
  • As an android developer, I assure you that org.json is available in the JVM distributed with the android platform (although I would not recommend using it).
Documentation:
  • All frameworks are well documented.
  • @AnkurJain You can solve your problem with this answer URL_http://stackoverflow.com/a/10868238/2412686 , adding the code org.apache.commons.lang3.StringEscapeUtils.unescapeJava("\\u00e9") (note that we use a newer version of the apache commons).
Community:
  • Hope it helps!
  • Shame on Google.)
Value:
  • You must surround the string value with double quotes.
  • N/A
Onlysentiment:
  • Just what I needed thanks!.
  • Exactly, I'm afraid so.
Performance:
  • GSON is a very powerful library for convert JSON-Java Object and viceversa..
  • And answer is somewhat bogus too :).Json.org's lib is not efficient in any way (and light-weight only if you count size of code itself).
Security:
  • Note: I have observed that this can "re-organize" the key value pairs order.
  • N/A
Bug:
  • The value is null.
  • getNames() doesn't exist at all i get a error telling the method doesn't exist.
Legal:
  • _As a consequence, JSON libraries are free to rearrange the order of the elements as they see fit.
  • Watch out for its bogus license, though
Usability:
  • The JSON standard dictates that keys must be strings: URL_http://json.org/ .

  • Performance: 11
    1. jsonexception: 1
      • For my taste it is a bit less elegant than having a specific JsonException but if is not possible otherwise that is still good.. details
    2. jsonarray: 1
      • It excels over org.json implementation by the fact that it simply extends HashMap for JSONObject and ArrayList for JSONArray making these objects by definition serializble and thus cacheable.. details
    3. gson: 2
      • GSON is a very powerful library for convert JSON-Java Object and viceversa... details
      • Well sometimes performance and usability can be at odds, but I've found GSON to be easier to use than alternatives like URL_http://jackson.codehaus.org/Home [Jackson] , URL_http://json.org/java/ [org.json] and others.. details

    1. parsing: 5
      • It might get a little more complicated when you're doing the arrays, if you prefer to do all of the parsing manually (also pretty easy) check out URL_http://www.json.org/ [ URL_http://www.json.org/ ] and download the Java source for the Json parser objects.. details
      • Parsing an XML is easy - you will find plenty of tutorials on it for Java such as: URL_http://www.seas.gwu.edu/~simhaweb/java/xml/xml.html [ URL_http://www.seas.gwu.edu /~simhaweb/java/xml/xml.html] Cheers!. details
      • Because of this, I don't think it gets much easier than first parsing the JSON string you have and then using the pretty-printing method URL_http://www.json.org/javadoc/org/json/JSONObject.html#toString%28int%29 [toString] mentioned in the comments above.. details
      • It dounds like it should be something like: CODETERM1 It's a bit more manual but have a look here: URL_http://json.org/java/ [ URL_http://json.org/java/ ] This will give you a JSONObject that is much easier to use than parsing the string yourself, but you will still have to drill into it and manually build your map.. details

      • Edit: There is not much you can do to simlify the JSON from your question except pretty-print it: CODESNIPPET_JAVA1 .. details
    4. iterator: 1
      • Take a look at the JSONObject reference: URL_http://www.json.org/javadoc/org/json/JSONObject.html [ URL_http://www.json.org/javadoc/org/json/JSONObject.html ] Without actually using the object, it looks like using either getNames() or keys() which returns an Iterator is the way to go.. details
    5. encoding: 2
      • For encoding data in CODETERM5 , yes CODETERM6 is a good approach, but I think that URL_http://www.json.org/ [CODETERM7] would be more easy to use.. details

      • Instead, retrieve the value, create a CODETERM5 from it and add it to the CODETERM6 .. details
      • Great... so did you use this suggested function?. details
      • When you need to access its value, use the functions that the URL_http://www.json.org/javadoc/org/json/JSONObject.html [JSONObject] provides.. details
      • Thanks for the useful comment.. details
      • Not sure what exact task you're working, but there are many JSON libraries for Java which can do this for you such as URL_http://json.org/java/ [json-in- java] and URL_https://code.google.com/p/google-gson/ [google-gson] .. details
      • Using the typed getMethods and chaining as I demonstrated here also helps clean up the code a lot!. details
      • if it is a JSONObject, the parameter you pass to the get method is the key; if it is a JSONArray, you pass in the index!. details
      • Once converted, you can use URL_http://www.json.org/javadoc/org/json/JSONObjec t.html#append%28java.lang.String,%20java.lang.Object%29 [JSONObject.append()] to append the key "age" with value "21" to it.. details
      • It's worth keeping in mind that Java's Serializable is just one implementation of serializing objects.. details
      • I suggest you to take a brief look at URL_http://www.json.org/ [json.org] in order to understand JSON syntax, which is pretty simple... Basically these are the possible JSON elements: CODESNIPPET_JAVA3 .. details

      • I recommend using JSON:On the server side, use one of the JSON libraries listed on URL_http://www.json.org [ URL_http://www.json.org ] .. details
      • You could also use $.get if that works for you .. details
      • Pretty simple.. details

    26. utf-8: 1
      • The best way if obviously to take this to whatever is outside your control and tell them to fix it :-) Workarounds One way to work around it is to create a servlet filter that removes all characters that are incompatible with both UTF-8 and ISO-8859-1 and replace them with JSON escapes: In the following fragment, replace '' with '\u00E9' so that any offending ISO-8859-1 character is safely transported in the 7-bits that are identical: Before: CODETERM1 After: CODETERM2 It's not as legible, but semantically speaking, it's the same, and any good JSON library should treat them identically.. details

      • Is not going to work because there is no object inside this JSON data called "Categories", instead it has a String element with value "Categories".. details
      • To achieve CDATA structure you can apply custom logic to handle string based values (and do it in the same way both for .net and java implementations).. details
      • Then I noticed that even when reading JSON responses from the URL_http://cloudbase.io [ URL_http://cloudbase.io ] APIs I transform the string successfully to a JSONOjbect.. details

      • A string is very much like a C or Java string.. details
      • _What is the right way to serialize this simple object to JSON string using classes from CODETERM5 package?_ Thank you for help!. details

      • :-/ So I understand that you can convert JSON strings to strings and handle JSON objects in general through the org.json bundle in Android, but here's my current situation: I need to take a JSON string from a certain URL (I'm already able to successfully do this) and make it into an array.. details
      • The reverse process is fairly simple, I mean converting a string to json object/array.. details

      • If you're using the URL_http://www.json.org/java/index.html [JSON.org-Java- implementation] , which is open source, you can just make JSONArray implement the CODETERM1 interface and add the following method to the class: CODESNIPPET_JAVA1 .. details
      • All this works because the JSONArray class is backed by a simple ArrayList, which is already iterable.. details
      • In using JSONArray , I have to declare a JSONObject?How can I extract the values from this.the values of latitude and longitude.. details
      • Search for JSONArray and JSONObject URL_http://www.json.org/javadoc/org/json/JSONArray.html [ URL_http://www.json.org/javadoc/org/json/JSONArray.html ] it's pretty easy to work with them.. details
      • It excels over org.json implementation by the fact that it simply extends HashMap for JSONObject and ArrayList for JSONArray making these objects by definition serializble and thus cacheable.. details
      • You want to check if totalResultsReturned 1. if it is, you should use .getJSONObject('Result') instead, and then construct a JSONArray with that object as the first value ( URL_http://www.json.org/javadoc/org/json/JSONArray.html) .. details
      • I suppose you have more than one Credential u want to get... with the org.json package you could use a JSONArray to get various values at the same time out of one JSON file.. details
    33. jsonobject: 7
      • But if you're working with Google App Engine, the classes JSONObject & XML can be found in com.google.appengine.labs.repackaged.org.json.. details
      • For example, in your case, you may create a JSONObject like the following and invoke its toString() function.. details
      • Assuming the JSONObject you mention is from URL_http://www.json.org/javadoc/org/json/JSONObject.html [this] , you can get the bytes like below CODESNIPPET_JAVA1 .. details
      • It seems like you must be using the CODETERM1 version of JSONObject (this is not the json.org version**).. details
      • I have had good luck using the JSON classes found here: URL_http://json.org/java/ [ URL_http://json.org/java/ ] You would essentially create a JSONObject instance like this: CODESNIPPET_JAVA1 .. details
      • JSONObject (from org.json) is one of the simple JSON libraries that you can use.. details
      • I recommend this library: URL_http://www.json.org/java/ [ URL_http://www.json.org/java/ ] You simply have to create a JSONObject from string, and get the name proprety.. details
    34. class: 5
      • It's good practice to create a model class containing the CODETERM13 's elements as member variables and providing a Constructor that takes the CODETERM14 containing the objects data values.. details
      • Using the JSONObject class from org.json, I could go down the road of doing something like this: CODESNIPPET_JAVA4 .. details
      • If your JSON data does not follow a specific structure, don't use GSON, but a regular JSON library (like the one from URL_http://json.org/ [json.org] ) that will give you an instance of a class like CODETERM1 , from which you can access data like CODETERM2 .. details
      • You just grab json, pass the class to want to deserialize into, and your class attributes will be matched to the JSON, but then again, everyone has their own requirements, maybe you can't afford the luxury to have pre-mapped classes on the deserializing side because things might be too dynamic on the JSON Generating side.. details
      • I've had a look at the classes there but I don't think I see a class that accepts the kind of notation I'm after.. details
    35. object: 11
      • URL_http://json.org/ [JSON-docs] says An object is an unordered set of name/value pairs So the way is getting the values in required order,rather than ordering CODETERM1 .. details
      • Use org.json.JSONObject URL_http://www.json.org/javadoc/org/json/JSONObject.html [ URL_http://www.json.org/javadoc/org/json/JSONObject.html ] You can create a JSON object and then use the put method to add your values.. details
      • edit This has the advantage that you can build your responses in different layers and return them as an object .. details
      • I personally use CODETERM12 if I have a bean object for a corresponding CODETERM13 String, otherwise CODETERM14 is more than enough.. details
      • if you have a simple flat model object with direct mapping to json, they are both brain dead simple.. details
      • (From [the JSON site]( URL_http://json.org) : "An object is an unordered set of name/value pairs"*) To have order, you must use an ordering construct (such as an array).. details
      • I would like to be able to store the object into memcache in an easy interface.. details
      • Thanks for that but I would prefer to not use any plugs in, I know there is a simple way that I could do it with a simple for each object in the array loop.I had it going before but I cant find it again.. details
      • I guess all of the libraries support toString() to convert the object to JSON string.. details
      • The internal form is an object having get() and opt() methods for accessing the values by index, and put() methods for adding or replacing values.. details
      • The internal form is an object having get() and opt() methods for accessing the values by name, and put() methods for adding or replacing values by name.. details
    36. ajax: 1

    37. apache: 1
      • commons.io library from apache is a great way to do this.. details
    38. serialization: 2
      • Alternatively, what memcache friendly serialization / deserialization technique do you use ?. details
      • In comparison, the serialization of data using JSON by the sender is relatively quick and compact because the structure of JSON reflects the structure of standard programming data types and the encoding mechanism adds only the minimum number of characters required to indicate the structure and value of the data.. details
    39. post: 2
      • To do so, I recommend checking out the simple Java library at URL_http://www.json.org/java/index.html [ URL_http://www.json.org/java/index.html ] Once you've generated your JSON, you can use something like the code below to POST it CODESNIPPET_JAVA1 .. details

    40. configuration: 1
      • In addition to all of this, I'm dealing with many providers for animal objects and I'll eventually be looking to have some succinct configuration format for describing the transformations (like, maybe, CODETERM1 ).. details
    41. data: 8
      • Let's go back to your question now that you've edited it So my question is, how can i do that?If user want to save 100+ data do i have to make 100+classes or elements?. details
      • There are micro-optimisations you can make, like data.ensureCapacity(stream.available()) and making your chunks 8K or 64K, etc, but really what would be better would be to serialise your data or save it to an SQL table after parsing, then use that except if you detect that the JSON file has been updated.. details
      • JSON is used to exchange data what you are trying to do is exchange JS which is not what it's intended for, nor is it safe to do so.. details
      • Changing the JSON data As simple as adding a CODETERM10 at the beginning and CODETERM11 at the end: CODESNIPPET_JAVA4 .. details
      • Since your JSON data looks more like an CODETERM6 than an CODETERM7 maybe you should try using URL_http://www.json.org/javadoc/org/json/JSONObject.html [CODETERM8] instead.. details
      • I find that the built-in JSON parser (org.json) parses the file very slowly, however once it's parsed, I can access and manipulate the data very quickly.. details
      • If you don't have all of the data and cannot instantiate the object, then you'll either need to pass empty values (which should signal a red flag to you) or fetch that data from the datastore first.. details
      • Doing so creates a great deal of extra padding around the actual data no matter which DTD is used.. details
    42. gson: 6
      • GSON is a very powerful library for convert JSON-Java Object and viceversa... details
      • I would comment that if you aren't using the automatic serialization elements from gson you may as well be using the smaller jar from json.org.. details
      • For the JSON could you use Google Gson ( URL_https://code.google.com/p/google- gson/ [ URL_https://code.google.com/p/google-gson/ ] ) is a very useful and easy library convert JSON-JAVA and vice-versa.. details
      • In my code, I am trying to convert a CODETERM1 into JSON using the URL_http://json.org/java/ [Java-JSON] library (however I'd also accept any answer using GSON as well).. details
      • Well sometimes performance and usability can be at odds, but I've found GSON to be easier to use than alternatives like URL_http://jackson.codehaus.org/Home [Jackson] , URL_http://json.org/java/ [org.json] and others.. details
      • Pretty much all alternatives from org.json list provide more convenient and simpler ways to work with JSON.Aside from Gson that some like, I would recommend URL_http://wiki.fasterxml.com/JacksonInFiveMinutes [Jackson] ; and flex-json and Svenson are other packages that seem decent.. details
    43. org.json: 10
      • Using the org.json library, you can chain together your get methods, like so: CODESNIPPET_JAVA1 .. details
      • From within this Constructor you can then read the values of the JSONObject like this: CODETERM15 For starters you can go with the org.json package and get familiar with URL_http://www.json.org [JSON] itself.. details
      • You could use a package like org.json URL_http://www.json.org/java/ [ URL_http://www.json.org/java/ ] Because you will need to use JSONObjects more often.. details
      • The org.json project created a generic URL_http://www.json.org/javadoc/org/json/JSONObject.html [JSONObject] class, which represents a single, generic key/value pair in a larger JSON representation.. details
      • URL_http://www.json.org/javadoc/org/json/JSONWriter.html [ URL_http://www.json.org/javadoc/org/json/JSONWriter.html ] URL_http://www.json.org/javadoc/org/json/JSONStringer.html [ URL_http://www.json.org/javadoc/org/json/JSONStringer.html ] Update: Also the class can't be private with the simple org.json lib.This works fine: CODESNIPPET_JAVA1 .. details
      • the implementation of each must use the org.json library to populate the fields of the object, and to build a JSON and from the object's fields, respectively.. details
      • I used org.json inbuilt methods to pretty print the data.. details
      • Good point, I had assumed it was the org.json classes.. details
      • org.json can not be resolved -- Eclipse.. details
      • Everything inside the objects is null However, If I use the CODETERM3 and CODETERM4 to pull them out piece by piece from the org.json jars, it works fine and the fields are populated accordingly.. details

    47. arrays: 2
      • Json Objects are basically just big nested sets of arrays and key-value pairs.. details
      • XML uses elements, attributes, and content text, while JSON uses unordered collections of name/value pairs and arrays of values.. details
    48. tree: 1
      • The answer is to use a URL_http://json.org/javadoc/org/json/JSONArray.html [JSONArray] as well, and to dive "deep" into the tree structure: CODESNIPPET_JAVA1 .. details

    51. logic: 2
      • I'm pretty sure it's not best practices to depend on exceptions thrown as part of logic in a method.. details
      • You can call URL_http://www.json.org/javadoc/org/json/JSONObject.html#names%28%29 [CODETERM1] on a CODETERM2 to get a CODETERM3 of the names of its elements - this would let you do logic on them or retrieve their corresponding values dynamically.. details

    33. arrays: 3
      • Are there any libraries or clever tricks for creating arrays of unknown type in Java?. details
      • As an interim solution, I've been able to render the JSONArray as an Object[], and then change the server-side code that interacts with these arrays to cast them as needed, but it's ugly, and it allows some JSON-yuck to seep into our code base.. details
      • Infoscoop's URL_http://code.google.com/p/infoscoop/source/browse/branches/3.0/ src/main/java/org/infoscoop/util/Xml2Json.java?r=629 [XML2JSON] class has a way of tagging elements that are arrays before doing the conversion, so that arrays can be properly mapped, even if there is only one child in the XML.. details
    34. double: 1
      • Refer to the JSON syntax diagrams at URL_http://www.json.org [ URL_http://www.json.org ] The fact that the double backslashes are giving you problems actually means that the software that is reading the files is broken.. details

  • Bug
    1. It should be of one of these types: Boolean, Double, Integer, JSONArray, JSONObject, Long, String, or the JSONObject.NULL object.
      • The values can be any of these types: Boolean, JSONArray, JSONObject, Number, and String, or the JSONObject.NULL object.
  • Usability
    1. Attempting to create a [org.json.JSONObject]( URL_http://www.json.org/javadoc/org/json/JSONObject.html ) from an (invalid JSON) String will produce the exception you are seeing.
      • Use org.json.JSONObject URL_http://www.json.org/javadoc/org/json/JSONObject.html [ URL_http://www.json.org/javadoc/org/json/JSONObject.html ] You can create a JSON object and then use the put method to add your values.
    2. The only problem with URL_http://www.json.org/java/ [JSON-in-Java] is that if your XML has a single child, but is an array, it will convert it to an object instead of an array.
      • The URL_http://www.json.org/java/ [JSON-in-Java] page on json.org has some great resources.
