Answer 1

请先自己做研究，这个网站不是为你做计算机科学的功课。因为我需要一些代表...

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);
