Wie konvertiert man ein JSON-Objekt in Java in das XML-Format?

public static java.lang.String toString(java.lang.Object object) throws JSONException

import java.io.*;
import org.json.*;
public class JSONtoXMLTest {
   public static void main(String[] args) throws JSONException {
      String json = "{employee : { age:30, name : Raja, technology:Java}}";
      //Convert JSON to XML
      String xml = convert(json, "root"); // This method converts json object to xml string
      System.out.println(xml);
   }
   public static String convert(String json, String root) throws JSONException {
      JSONObject jsonObject = new JSONObject(json);
      String xml = "<?xml version=\"1.0\" encoding=\"ISO-8859-15\"?>\n<"+root+">" + XML.toString(jsonFileObject) + "</"+root+">";
      return xml;
   }
}

<!--?xml version="1.0" encoding="ISO-8859-15"?--><?xml version="1.0" encoding="ISO-8859-15"?>
<root>
   <employee>
      <name>Raja</name>
      <technology>Java</technology>
      <age>30</age>
   </employee>
</root>
