The following example shows the usage of java.util.Properties.storeToXML() method.

package com.tutorialspoint;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.*;

public class PropertiesDemo {
   public static void main(String[] args) {
      Properties prop = new Properties();

         FileInputStream fis = new FileInputStream("properties.xml");

         // store the properties in the specific xml
         prop.storeToXML(fos, "Properties Example");

         // print the xml
         while (fis.available() > 0) {
            System.out.print("" + (char) fis.read());

<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
