Java 将JSON数组追加到JSONObject

如何附加：

JSONObject jsonObj = new JSONObject("string");
jsonObj.toString();

"employees":[{"firstname":"stack","lastname":"overflow"}, {"firstname":"Happy","lastname":"Coding"}]

添加到上面的json对象

我想去

{"firstname":"Gloomy","lastname":"Sunday"}

请先自己研究一下，这个网站不是为你做计算机科学作业的。只是因为我需要一些代表

"employees":[{"firstname":"stack","lastname":"overflow"}, {"firstname":"Happy","lastname":"Coding"}, {"firstname":"Gloomy","lastname":"Sunday"}]

upon jsonObj.toString();

绑定到现有employees对象中，而不是创建新对象。您确定First代码示例会生成写在其末尾的字符串吗？这些数据来自哪里？

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();
        }
    }
}

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