With a few lines of code you can check if an E-Mail address ist valid or not. The most import part ist our pattern:

String pattern = "([a-z0-9_.-]+@[a-z0-9-]+\\.[a-z]{2,6})";

import java.util.regex.*;

public class EmailCheck {

	public static void main(String[] args) {

		String eMail = "youremailyoursite.com"; 
		
		String pattern = "([a-z0-9_.-]+@[a-z0-9-]+\\.[a-z]{2,6})";
		if(eMail.matches(pattern)){
			System.out.println("Your E-Mail address is valid");
		}else{
			System.out.println("You entered a not valid E-Mail address");
		}

	}
