What is the best Java email address validation method? [closed]

Answer 1

This is the best method:

public static boolean isValidEmail(String enteredEmail){
        String EMAIL_REGIX = "^[\\\\w!#$%&’*+/=?`{|}~^-]+(?:\\\\.[\\\\w!#$%&’*+/=?`{|}~^-]+)*@(?:[a-zA-Z0-9-]+\\\\.)+[a-zA-Z]{2,6}$";
        Pattern pattern = Pattern.compile(EMAIL_REGIX);
        Matcher matcher = pattern.matcher(enteredEmail);
        return ((!enteredEmail.isEmpty()) && (enteredEmail!=null) && (matcher.matches()));
    }
