How to store properties as XML file?

In the previous example, How to load properties from XML file? we read properties from XML file. Now it's the turn on how to store the properties as XML file.

package com.javacoderanch.example.io;

import java.io.FileOutputStream;
import java.util.Properties;

public class PropertiesToXml {
    public static void main(String[] args) throws Exception {
        Properties properties = new Properties();
        properties.setProperty("database.type", "mysql");
        properties.setProperty("database.url", "jdbc:mysql://localhost/mydb");
        properties.setProperty("database.username", "root");
        properties.setProperty("database.password", "root");

        FileOutputStream fos = new FileOutputStream("database-configuration.xml");
        properties.storeToXML(fos, "Database Configuration", "UTF-8");
    }
}

The saved XML file will look like the properties file below:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
  <properties>
    <comment>Database Configuration</comment>
    <entry key="database.password">root</entry>
    <entry key="database.url">jdbc:mysql://localhost/mydb</entry>
    <entry key="database.type">mysql</entry>
    <entry key="database.username">root</entry>
  </properties
