How to create and store property file dynamically?

We can also create property files 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. Below example shows how to create it.

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 MyPropertyFileStore {

	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.properties");
			prop.store(os, "Dynamic Property File");
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		}
		
	}
}
