我們如何在Java中合併兩個JSON物件？

import java.util.Date;
import org.json.simple.JSONObject;
public class MergeJsonObjectsTest {
   public static void main(String[] args) {
      JSONObject jsonObj = new JSONObject(); // first json object
      jsonObj.put("Name", "Adithya");
      jsonObj.put("Age", 25);
      jsonObj.put("Address", "Hitech City");
      JSONObject jsonObj1 = new JSONObject(); // second json object
      jsonObj1.put("City", "Hyderabad");
      jsonObj1.put("DOB", new Date(104, 3, 6));
      jsonObj.putAll(jsonObj1); // merging of first and second json objects
      System.out.println(jsonObj);
   }
}

{"Address":"Hitech City","DOB":Tue Apr 06 00:00:00 IST 2004,"City":"Hyderabad","
Age":25,"Name":"Adithya"}
