由于课程设计的缘故，提前做了个身份证查询小工具。
技术含量并不高，"出生日期、性别、年龄"都是根据身份证的算法算出来的,身份证号码18位数对应不同的含义，大家百度查一下即可。
"发证地区"理论上也可以算出来，但是地区数据过于庞大，短时间内写出来是不可能的，看了下java的网络编程和爬虫技术，也参考了网上一些代码，抓取的是ip138的网页，然后返回地区结果。
对于正则表达式和网络编程方面的知识只学了两条天时间，因为还没有深入，正则表达式写得特别烂，但是能正确抓取所要的信息，见谅
GUI方面，为了方便，安装了WindowBuilder插件。
代码引用了两个图片，一个是icon，一个是label定义的背景图片，在此不上传了，大家进行替换或者删减即可
