updating json object using java [closed]

Answer 1

If you are using the JsonObject class it is immutable

So i believe you have to duplicate the object and change the value like this:

JSONObject object=new JSONObject(jsonstring);
JSONObject childobject=object.getJSONObject("XXXX");

JSONObject modifiedjson=new JSONObject();
modifiedjson.put("type",childobject.get("type"));
modifiedjson.put("value","newvalue");  // Add new value of XXXX here

Answer 2

Parse the JSON and call the particular Key needs to be updated and set the value for the key. Please be more specific.

Create a new JSON Object

private JSONObject Data = new JSONObject;

public Test(){

try {

Data.put("address", username);
    }

catch (JSONException e) {

  // TODO Auto-generated catch block

  e.printStackTrace();
    }
}
