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。

总结：在这学期中学习了面向对象程序设计这门课程，学会了如何去构建GUI界面，知道了什么是封装以及封装的机制（类与对象）也知道了继承和接口的重要性能够简单的做一些异常处理，了解到泛型程序设计可以让程序更安全，更可读。最后也知道了并发能够让程序任务并行执行。这学期老师引入助教（这在我的学习生活中并没有遇到过），助教学长能够兢兢业业的为我们付出，为我们讲解不懂的知识，而且还在实验中设立自主编程练习，这样可以更好更有效地提升我们的能力。通过本学期的学习，我收获了很多。感谢老师以及学长的帮助/。
