JSONObject类是键-值对的无序集合。它提供了通过键访问值和放置值的方法。支持以下类型-

  • 布尔型

  • JSONArray

  • JSONObject

  • JSONObject.NULL对象

import org.json.JSONArray;
import org.json.JSONObject;

public class JSONDemo {
   public static void main(String[] args) { 
      JSONObject jsonObject = new JSONObject();
      jsonObject.put("Name", "Robert");
      jsonObject.put("ID", 1);
      jsonObject.put("Fees", new Double(1000.21));
      jsonObject.put("Active", new Boolean(true));
      jsonObject.put("Other Details", JSONObject.NULL);

      JSONArray list = new JSONArray();
      list.put("foo");
      list.put(new Integer(100));
      jsonObject.put("list",list);
      System.out.println(jsonObject);
   }
}

输出

{"Active":true,"Other Details":null,"ID":1,"Fees":1000.21,"list":["foo",100],"Name":"Robert"}
