請做研究這自報家門，這網站不是在這裏爲你做你的計算機科學作業。只是因爲我需要一些代表...

public class ex{ 
    void example(){ 
     try{ 
      JSONObject jobj = new JSONObject("[{firstname:stack,lastname:overflow}]"); 
      JSONObject jobj2 = new JSONObject("[{firstname:Happy,lastname:Coding}]"); 
      JSONArray jarray = new JSONArray(); 
      jarray.put(jobj); 
      jarray.put(jobj2); 
     }catch(JSONException e){ 
      e.printStackTrace(); 
     } 
    } 
} 

Answer 2

JSONObject jsonObj = new JSONObject(); 
JSONObject jo1 = new JSONObject("{"firstname":"Gloomy","lastname":"Sunday"}"); 
jsonObj.append("employees", jo1);
