根据身份证号,使用Java编写程序获取年龄、性别、出生日期http://www.bieryun.com/847.html
程序员必须要有一个好的思想,代码有时候就体现了一个人的灵魂,所以理解需求比技术更重要!

- * 判断18位身份证的合法性
- * </p>
- * 根据〖中华人民共和国国家标准GB11643-1999〗中有关公民身份号码的规定,公民身份号码是特征组合码,由十七位数字本体码和一位数字校验码组成。
- * 排列顺序从左至右依次为:六位数字地址码,八位数字出生日期码,三位数字顺序码和一位数字校验码。
- * <p>
- * 顺序码: 表示在同一地址码所标识的区域范围内,对同年、同月、同 日出生的人编定的顺序号,顺序码的奇数分配给男性,偶数分配 给女性。
- * </p>
- * <p>
- * 1.前1、2位数字表示:所在省份的代码; 2.第3、4位数字表示:所在城市的代码; 3.第5、6位数字表示:所在区县的代码;
- * 4.第7~14位数字表示:出生年、月、日; 5.第15、16位数字表示:所在地的派出所的代码;
- * 6.第17位数字表示性别:奇数表示男性,偶数表示女性;
- * 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。
- * </p>
- * <p>
- * 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
- * </p>
- * <p>
- * 2.将这17位数字和系数相乘的结果相加。
- * </p>
- * <p>
- * 3.用加出来和除以11,看余数是多少?
- * </p>
- * 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
- * 2。
- * <p>
- * 5.通过上面得知如果余数是2,就会在身份证的第18位数字上出现罗马数字的Ⅹ。如果余数是10,身份证的最后一位号码就是2。
