Question

I want to create a Json object like the following:

{"name": "Maximum", "children": [
                    {"name": "where", "size": 299},
                    {"name": "xor", "size": 354},
                    {"name": "_", "size": 264}
                    ]
}

Which library to use to create the above Json string and how should the code look like?

Answer 1

Try gson . It has good support for this. Check out this user guide.

Your class structure would look like:

class Parent{
        String name;
        Children[] children;
//getter and setter
    }
    class Children{
        String name;
        int size;
//getter and setter
    }

then in your code:

   Parent parent = new Parent();
    //poppulate parent object with required values 
    Gson gson = new Gson();
    gson.toJson(parent);
