     * 6.第17位数字表示性别：奇数表示男性，偶数表示女性；
     * 097
     * 7.第18位数字是校检码：也有的说是个人信息码，一般是随计算机的随机产生，用来检验身份证的正确性。校检码可以是0~9的数字，有时也用x表示。

     * 第十八位数字(校验码)的计算方法为： 1.将前面的身份证号码17位数分别乘以不同的系数。从第一位到第十七位的系数分别为：7 9 10 5 8 4

     * 2 1 6 3 7 9 10 5 8 4 2

     * 106
     * <p>
     * 107
     * 3.用加出来和除以11，看余数是多少？
     * 108
     * </p>
     * 109
     * 4.余数只可能有0 1 2 3 4 5 6 7 8 9 10这11个数字。其分别对应的最后一位身份证的号码为1 0 X 9 8 7 6 5 4 3

测试：

    public static void main(String[] args) throws Exception {
        String idcard15 = "370283790911703";//15位
        String idcard18 = "37078119790127719x";//18位
        IdcardValidator ie15 = new IdcardValidator(idcard15);
        IdcardValidator ie18 = new IdcardValidator(idcard18);
        System.out.println(ie15.toString());
        System.out.println(ie18.toString());
    }

 结果：
