任务2：综合编程练习
练习1：设计一个用户信息采集程序，要求如下：
（1） 用户信息输入界面如下图所示:
（1）用户点击提交按钮时，用户输入信息显示控制台界面；
（2）用户点击重置按钮后，清空用户已输入信息；
（3）点击窗口关闭，程序退出。

练习2：采用GUI界面设计以下程序：
l 编制一个程序，将身份证号.txt 中的信息读入到内存中；
l 按姓名字典序输出人员信息；
l 查询最大年龄的人员信息；
l 查询最小年龄人员信息；
l 输入你的年龄，查询身份证号.txt中年龄与你最近人的姓名、身份证号、年龄、性别和出生地；
l 查询人员中是否有你的同乡。
l 输入身份证信息，查询所提供身份证号的人员信息，要求输入一个身份证数字时，查询界面就显示满足查询条件的查询结果，且随着输入的数字的增多，查询匹配的范围逐渐缩小。
