Program: How to load Properties file from the classpath?

This example shows how to load properties file from application classpath. Here we are using this.getClass().getResourceAsStream() to load the properties file in the classpath. Make sure that the properties file is available in the class path.

package com.java2novice.properties;

import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

public class MyPropWithinClasspath {

	private Properties prop = null;
	
	public MyPropWithinClasspath(){
		
		InputStream is = null;
		try {
			this.prop = new Properties();
			is = this.getClass().getResourceAsStream("/sample.properties");
			prop.load(is);
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
	
	public String getPropertyValue(String key){
		return this.prop.getProperty(key);
	}
	
	public static void main(String a[]){
		
		MyPropWithinClasspath mpc = new MyPropWithinClasspath();
		System.out.println("db.host: "+mpc.getPropertyValue("db.host"));
		System.out.println("db.user: "+mpc.getPropertyValue("db.user"));
		System.out.println("db.password: "+mpc.getPropertyValue("db.password"));
	}
}

db.host=appdomain.java2novice.com
db.user=java2novice
db.password=mypassword
db.service=orcl

db.host: appdomain.java2novice.com
db.user: java2novice
db.password: mypassword
