E-Mail validation with Java and regular expressions (regex)
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");
}
}
}
