toJSONString() is undefined for the type JSONObject

Question

My code to create a new JSONObject and write to a file:

JSONObject obj = new JSONObject();
obj.put(\"name\", \"abcd\");
obj.put(\"age\", new Integer(100));
J         


        

Answer 1

The JSONObject class doesn't have a toJSONString() method. Instead it overrides the toString() method to generate json.

To get the json representation of the object, simply use obj.toString().
