Program: How to store property file as xml file?


Description:

We can also create property files in xml format dynamically. First creat Properties object, add all property key-value pair by using setProperty() method. Then write this file to FileOutputStream object to store is as a property file as xml. Call storeToXML() method to store it to the file system. Below example shows how to create it.


Code:
package com.java2novice.files;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.util.Properties;

public class MyFileXmlStore {
	
	public static void main(String a[]) throws IOException{
		
		OutputStream os = null;
		Properties prop = new Properties();
		prop.setProperty("name", "java2novice");
		prop.setProperty("domain", "www.java2novice.com");
		prop.setProperty("email", "[email protected]");
		try {
			os = new FileOutputStream("MyProp.xml");
			prop.storeToXML(os, "Dynamic Property File");
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		}
		
	}
}

Output:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<properties>
<comment>Dynamic Property File</comment>
<entry key="email">[email protected]</entry>
<entry key="name">java2novice</entry>
<entry key="domain">www.java2novice.com</entry>
</properties>

Difference between super() and this()
super() is used to call super class constructor, whereas this() used to call constructors in the same class, means to call parameterized constructors.
