I have json libs (json-simple) and trying to make jsonarray from jsonobjects. My aim to make JSON string look something like string below 

[{"name": "somename","surname": "somesurname"},
 {"name": "somename2","surname": "somesurname2"}]

and it will have possibility of adding new objects in the same array.

This what im "hardcoding" now. 

    JSONObject obj= new JSONObject();
    JSONArray arr = new JSONArray();

    for(int i = 0 ; i< arr.size() ; i++)
    {
      obj.put("name", name);
      obj.put("surname", surname);

      arr.add(obj);
      obj= new JSONObject();
    }

    What's your question? Why do you use i to iterate over an empty array? Where are name and surname declared? Commented Sep 11, 2015 at 12:53

  • One suggestion because you do not use Gson? Here are two examples: stackoverflow.com/questions/18993414/… and stackoverflow.com/questions/9186806/… I hope this helps. Commented Sep 11, 2015 at 14:22
