How to Create XML file and Save XML Data in Java?

In previous tutorial,   we learned How to Read XML Data in Java ?, Now in this Tutorial I will tell you how you can save your data in the XML File format.

At the end of the Example our following XML file with the name student.xml will created.

<school>
      <student rollno="1">
          <firstname>NAVEEN</firstname>
          <lastname>RAWAT</lastname>
          <age>16</age>
      </student>
</school>

Following is the Java File with the name XmlWritterDemo.java which are saving the data with the help of DOM Parser

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 XmlWritterDemo {
    public static void main(String[] args) {
        try{
            DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
            DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
            
            Document doc = dBuilder.newDocument();
            Element root = doc.createElement("SCHOOL");
            doc.appendChild(root);
            
            Element student = doc.createElement("STUDENT");
            root.appendChild(student);
            
            Attr attr = doc.createAttribute("ROLLNO");
            attr.setValue("1");
            student.setAttributeNode(attr);
            
            Element fname = doc.createElement("FIRSTNAME");
            fname.appendChild(doc.createTextNode("NAVEEN"));
            student.appendChild(fname);
            
            Element lname = doc.createElement("LASTNAME");
            lname.appendChild(doc.createTextNode("RAWAT"));
            student.appendChild(lname);
            
            Element age = doc.createElement("AGE");
            age.appendChild(doc.createTextNode("16"));
            student.appendChild(age);
            
            TransformerFactory transformerFactory = TransformerFactory.newInstance();
            Transformer transformer = transformerFactory.newTransformer();
            DOMSource source = new DOMSource(doc);
            StreamResult result = new StreamResult(new File("student.xml"));
            
            transformer.transform(source, result);
            
            System.out.println("File Successfully Saved");
            
            
        }catch(ParserConfigurationException pce){        
                pce.printStackTrace();
        }catch(TransformerException te){
            te.printStackTrace();
        }
    }
