    To create XML file in Java,here we are using DOM parser. By using the below code you can easily create XML file.

    Write the below Java class to create a XML file:

    CreateXMLFile.java

    package com.babita;
    
    import java.io.File;
    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;
    
    import org.w3c.dom.Attr;
    import org.w3c.dom.Document;
    import org.w3c.dom.Element;
    
    public class CreateXMLFile {
    
        public static void main(String args[]) {
    
          try {
    
            DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
            DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
    
            // root elements
            Document doc = docBuilder.newDocument();
            Element rootElement = doc.createElement("company");
            doc.appendChild(rootElement);
    
            // employee elements
            Element employee = doc.createElement("employee");
            rootElement.appendChild(employee);
    
            // set attribute to employee element
            Attr attr = doc.createAttribute("id");
            attr.setValue("1");
            employee.setAttributeNode(attr);
    
            // you can also use the below way toset attribute to employee element
            // employee.setAttribute("id", "1");
    
            // firstname elements
            Element firstname = doc.createElement("firstname");
            firstname.appendChild(doc.createTextNode("babita"));
            employee.appendChild(firstname);
    
            // lastname elements
            Element lastname = doc.createElement("lastname");
            lastname.appendChild(doc.createTextNode("dhami"));
            employee.appendChild(lastname);
    
            // emailId elements
            Element emailid = doc.createElement("emailid");
            emailid.appendChild(doc.createTextNode("babita.dhami@gmail.com"));
            employee.appendChild(emailid);
    
            // designation elements
            Element designation = doc.createElement("designation");
            designation.appendChild(doc.createTextNode("software engineer"));
            employee.appendChild(designation);
    
            // write the content into xml file
            TransformerFactory transformerFactory = TransformerFactory.newInstance();
            Transformer transformer = transformerFactory.newTransformer();
            DOMSource source = new DOMSource(doc);
            StreamResult result = new StreamResult(new File("C:\\myDetail.xml"));
    
            // Output to console for testing, if you want see output on console
            // StreamResult result = new StreamResult(System.out);
    
            transformer.transform(source, result);
    
            System.out.println("XML file created!");
    
          } catch (ParserConfigurationException pce) {
            pce.printStackTrace();
          } catch (TransformerException tfe) {
            tfe.printStackTrace();
          }
        }
    }
    

    Output:

    The following XML file named myDetail.xml will be created after running the above example.

    <?xml version="1.0" encoding="UTF-8" standalone="no" ?> 
    <company>
        <employee id="1">
            <firstname>babita</firstname>
            <lastname>dhami</lastname>
            <emailid>babita.dhami@gmail.com</emailid>
            <designation>software engineer</designation>
        </employee>
    </company>
    

    Hope this will help you :)
