        System.out.println(emailString.matches(email1));
        System.out.println(emailString.matches(email2));

        //匹配手机号
        String phoneString = "15976875621";

        //11位=3位+8位
        String phone = "((13[0-9])|(15[^4,\\D])|(18[0,2,5-9]))\\d{8}";

        System.out.println(phoneString.matches(phone));
