private Matcher matcher;
private static final String EMAIL_PATTERN =
"^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";
public EmailValidator(){
pattern = Pattern.compile(EMAIL_PATTERN);
}
/**
* Validate hex with regular expression
* @param hex hex for validation
* @return true valid hex, false invalid hex

return matcher.matches();
}
}
