Parsing JSON Strings to Objects in Java ME

Question:

Is there a concise way to convert a JSON string into an object representation in Java ME? The conventional method requires multiple lines of tedious coding, as shown below:

Object n = create("new");
setString(p, "name", "MyNode");
setInteger(p, "width", 200);
setInteger(p, "height", 100);

Answer:

Consider utilizing external libraries for enhanced JSON handling capabilities. One highly recommended library for Java ME is:

http://code.google.com/p/json-simple/

This lightweight library makes JSON parsing efficient and effortless, enabling you to convert a JSON string into an object in a single line of code:

JSONObject json = (JSONObject)new JSONParser().parse("{\"name\":\"MyNode\", \"width\":200, \"height\":100}");

You can then retrieve specific data fields from the parsed object:

System.out.println("name=" + json.get("name"));
System.out.println("width=" + json.get("width"));
