How to create XML file in Java

package com.example.TestApp;

import java.io.File;
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;

public class CreateXMLFileJava {

 public static void main(String[] args) throws ParserConfigurationException, 
                                               IOException, 
                                               TransformerException
    {
     // 1.Create a DocumentBuilder instance
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder dbuilder = dbFactory.newDocumentBuilder();

    // 2. Create a Document from the above DocumentBuilder.
    Document document = dbuilder.newDocument();

    // 3. Create the elements you want using the Element class and its appendChild method.   

   // root element
    Element users = document.createElement("users");
    document.appendChild(users);   

    // child element
    Element user = document.createElement("user");
    users.appendChild(user);  

    // Attribute of child element
    user.setAttribute("uid", "1");   

    // firstname Element
    Element firstName = document.createElement("firstName");
    firstName.appendChild(document.createTextNode("Interview"));
    user.appendChild(firstName);   

    // lastName element
    Element lastName = document.createElement("lastName");
    lastName.appendChild(document.createTextNode("Bubble"));
    user.appendChild(lastName);   

    // email element
    Element email = document.createElement("email");
    email.appendChild(document.createTextNode("admin@interviewBubble.com"));
    user.appendChild(email);   

    // write content into xml file   

    // 4. Create a new Transformer instance and a new DOMSource instance.
   TransformerFactory transformerFactory = TransformerFactory.newInstance();
   Transformer transformer = transformerFactory.newTransformer();
   DOMSource source = new DOMSource(document);

   // 5. Create a new StreamResult to the output stream you want to use.
   StreamResult result = new StreamResult(new File("/Users/admin/Desktop/users.xml"));
   // StreamResult result = new StreamResult(System.out); // to print on console

   // 6. Use transform method to write the DOM object to the output stream.
   transformer.transform(source, result);  

   System.out.println("File created successfully");
 }
