程序运行截图如下：
===一开始的进去的界面
===程序设定的是输入1~5的题数，如果输入不正确会提示重新输入~~
===输入正确后按开始答题按钮，按钮会消失，并且输入题数的框是不可改的。用户只能在输入答案的框内输入，当题数答完后，输入题数的框可以重新输入，开始答题的按钮会重新出现~~~
===每答完一题，界面会显示正确答案和判断对错，并且显示答对的题数和答错的题数，答题结束后，界面显示用户答题的所用时间，然后用户可以重新输入答题的题数，重新开始或者按退出按钮退出~~~
===作业中的照片，人太丑，不敢露脸~~~
这个结对作业，我们估计的总用时是8-10小时，结果我们用了7个小时完成了这个实验，比预计的快了一个小时。
1.我们用的是Eclipse（java）进行编程的
2.我们完成的内容是：
（2）.可以出表达式里含有负整数（负整数最小不小于-100）的题目，且负数需要带括号，用户输入的结果不用带括号。如： 2*（-4） = -8
（3）用户答题结束以后，程序可以显示用户答题所用的时间
（4）用户可以选择出题的个数（最多不能超过5个题目），答题结束可以显示用户答错的题目个数和答对的题目个数
（6）程序可以出单个整数阶乘的题目：如：4!=24
3.本次结对的同学为 ：
201306114305 欧其锋 博客：http://www.cnblogs.com/ouqifeng/
201306114305 吕日荣 博客：http://www.cnblogs.com/Russelling/
4.这个编程过程中，框架界面是共同完成的，欧其锋完成的功能是（2）（3），吕日荣完成的功能是（4）（6）；
总结：通过这次实验，我觉得我们的收获还是挺大的，首先这个实验要求我们能够提高效率，因为结对的作用就是为了提高工作的效率，这方面我们还是做到了，我们用的时间比预想的时间少了。其次这个实验其实最难的部分是界面的实现，做界面这个东西，我们运用到了WindowBuilder,这个东西让我们在做界面的时候提高了效率，也提高了容错率，在这方面我觉得这个东西帮到了我们很多。最后就是功能与面板之间的一个支持方面的难点，我们在这方面使用了很多很多时间去解决这个问题。 我们觉得，这个实验其实只是一个开始，毕竟我们寻找bug的能力还有所缺陷，我们想到的范围还是比较狭隘的，我们希望这个实验是我们提高的一个阶段，当老师寻找到bug的时候，我们会继续去思考，解决这些bug，完善这个程序。
这只是1.0的版本，后期会有功能更加完善的功能的2.0,3.0版，请期待！
bug1已经修改好了，代码更新了，解决方法是将NumberFormatException加入一个异常处理，除了输入题数的框修改外，输入答案的框也进行了异常处理；
修复后的截图如下：
