Possible Duplicate: Turn C# object into a JSON string in .NET 4 In the Java, I have a code to convert java object to JSON string. Java EE 7 has a JSON API in javax.json, see the Javadoc. The JSON module offers two methods - stringify(), which turns a JavaScript object into a JSON String, and parse(), which parses a JSON string and returns a JavaScript object. I don't know which json library are you using, but try to look for method something like: isEmptyObject() Calls a Java method by matching the argument signature, using reflection. After clicking the submit button a sendJSON() is called which is defined below. JSON objects are associative containers, wherein a string key is mapped to a value (which can be a number, string, boolean, array, an empty value null, or even another object). The {} in JSON represents an object and should map to a Java Map or just some JavaBean class. it consists of three libraries: Jackson Extracts json object from a json string based on json path specified, and returns json string of the extracted json object. it consists of three libraries: Jackson In this tutorial, Ill show you how to write JSON data to a file using JSON.simple . the first being a build number and the second being a build hash.
