在java中创建嵌套的json对象

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

public class Main {
    public static void main(String[] args) {
        JSONObject jsonObject = new JSONObject();
        
        try {
            // 添加基本类型数据
            jsonObject.put("name", "John");
            jsonObject.put("age", 30);
            jsonObject.put("married", true);
            
            // 添加嵌套的JSON对象
            JSONObject address = new JSONObject();
            address.put("street", "123 Main St");
            address.put("city", "New York");
            address.put("country", "USA");
            jsonObject.put("address", address);
            
            // 添加嵌套的JSON数组
            JSONArray hobbies = new JSONArray();
            hobbies.put("reading");
            hobbies.put("traveling");
            hobbies.put("cooking");
            jsonObject.put("hobbies", hobbies);
            
            System.out.println(jsonObject.toString());
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
}
