        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);
        }
    
    
        public boolean validate(final String email) {
    
            matcher = pattern.matcher(email);
