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。

练习3：采用GUI界面设计以下程序
l 编写一个计算器类，可以完成加、减、乘、除的操作
l 利用计算机类，设计一个小学生100以内数的四则运算练习程序，由计算机随机产生10道加减乘除练习题，学生输入答案，由程序检查答案是否正确，每道题正确计10分，错误不计分，10道题测试结束后给出测试总分；
l 将程序中测试练习题及学生答题结果输出到文件，文件名为test.txt。

任务3：本学期课程已结束，请汇总《面向对象程序设计课程学习进度条》的数据，统计个人专业能力提升的数据。并从学习内容、学习方法、学习心得几个方面进行课程学习总结，也希望你对课程的不足提出建议和意见。
实验总结：
实验结束了，我觉得课程确实不错，但是作业量还是有点多，所以最后作业效率感觉没那么高了。
