public static boolean isEmail(String strEmail) {
        String strPattern = "^[a-zA-Z][\\w\\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\\w\\.-]*[a-zA-Z0-9]\\.[a-zA-Z][a-zA-Z\\.]*[a-zA-Z]$";

        Pattern p = Pattern.compile(strPattern);
        Matcher m = p.matcher(strEmail);
        return m.matches();
    }
