What is the best way to combine (merge) two JSONObjects?

    \"one\": \"1\",

Answer 1

json objects to be merge in that new json object like this.

    JSONObject jObj = new JSONObject();
    jObj.put("one", "1");
    jObj.put("two", "2");
    JSONObject jObj2 = new JSONObject();
    jObj2.put("three", "3");
    jObj2.put("four", "4");


    JSONParser p = new JSONParser();
    net.minidev.json.JSONObject o1 = (net.minidev.json.JSONObject) p
                        .parse(jObj.toString());
    net.minidev.json.JSONObject o2 = (net.minidev.json.JSONObject) p
                        .parse(jObj2.toString());

    o1.merge(o2);

    Log.print(o1.toJSONString());

now o1 will be the merged json object. you will get the output like this ::

{"three":"3","two":"2","four":"4","one":"1"}
