在java中使用JSONObject和JSONArray创建Json文档

import org.json.JSONObject;

public class Main {
    public static void main(String[] args) {
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("name", "John");
        jsonObject.put("age", 25);
        jsonObject.put("isStudent", true);

        System.out.println(jsonObject.toString());
    }
}

{"name":"John","age":25,"isStudent":true}

import org.json.JSONArray;

public class Main {
    public static void main(String[] args) {
        JSONArray jsonArray = new JSONArray();
        jsonArray.put("apple");
        jsonArray.put("banana");
        jsonArray.put("orange");

        System.out.println(jsonArray.toString());
    }
}

["apple","banana","orange"]
