  56.                             JSONArray jsonArray = response.getJSONArray("0"); //here what i do 
  57.   
  58.                             for (int i = 0; i < jsonArray.length(); i++) {  
  59.                                 JSONObject employee = jsonArray.getJSONObject(i);  
  60.   
  61.                                 //String firstName = employee.getString("firstname");  
  62.                                 //int age = employee.getInt("age");
