Try to use gson if you have to work a lot with JSON in java. Gson is a Java library that can be used to convert Java Objects into JSON representation. It can also be used to convert a JSON string to an equivalent Java object.

Here is a small example:

Gson gson = new Gson();
gson.toJson(1);            ==> prints 1
gson.toJson("abcd");       ==> prints "abcd"
gson.toJson(new Long(10)); ==> prints 10
int[] values = { 1 };
gson.toJson(values);       ==> prints [1]
