Email Validation Using RegularExpression

We can validate Email using regularExpression support given by JDK

  EmailValidation.java

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class EmailValidation{
     
    public static void main(String args[])
    {
      Pattern pattern;
      Matcher matcher;

String email="suraj20p@gmail.com";
      String EMAIL_PATTERN = "^[_A-Za-z0-9]+(\\.[_A-Za-z0-9]+)*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";

   
     //compile our pattern
     pattern = Pattern.compile(EMAIL_PATTERN);
     //pass our email to matcher,so that it can be checked whether pattern is matching or not
     matcher = pattern.matcher(email);
    
     //check whether string is matched or not
      boolean result= matcher.matches();

      if(result)
           System.out.println("Email Validated Successfully");
      else System.out.println("Invalid Email Address");
    }
}
