程序流程图如下:
实现界面截图:
首次登陆的用户界面：
当点击初级版时，进入初级版题型选择界面：
当点击整数与整数型时，进入实战界面初级版整数与整数型界面：
当输入总题数时，就可以点击开始做题（时间以及相应的答对错提数也会相应的计算）：
答错题目的情况：
答对题目的情况亦如上（只是答对了就不会显示正确答案）
当答题结束后弹出答题结束的对话框（当答题超时或答题者自动退出时也会弹出类似的对话框）：
其他版本以及实战界面同上所述。
结对同伴：201306114353 李豌湄 博客：http://www.cnblogs.com/leewanmei/
结伴分工情况：豌湄和我先一起讨论界面如何设置以及该程序需要实现怎样的功能，然后豌湄主要做中级版和高级版的算法，我主要做界面以及初级版的内容，最后一起讨论未能实现的功能，并加以改善和完成该程序。
随机四则运算(带界面)的主要功能
①可以分级别进行实战（初级版、中级版、高级版）；
②当用户不懂三个级别的内容可以通过帮助来解决；
③实战界面中有如下功能:
(1)答题者可以输入答题数；
(2)当每做一题都有计时，当时间到达就提示答题者，并弹出相应的对话框来告诉答题者的答题情况；
(3)答题过程中答题者可以随时观察到自己答该题的时间情况以及之前答对错题目的个数；
(4)做完题时，答题者可以知道总答题时间，以及答题的情况；
(5)当答题者中途退出时，答题者也可以知道答题的相应情况；
(6)当答题者输入该题答案时，通过键盘的回车符，可以显示该题的对错，如果答错还会有相应的正确答案的提示。
程序的优点：
①可以让答题者根据自身的情况选择相应的实战模块；
②可以提高答题者的计算能力，检测答题者的答题时间；
③答题者可以随时观察自己在答题过程中答对题数以及答错的题数，还有本题的答题时间；
④可以让答题者输入答题的题数；
⑤答题者答题过程中程序可以监测到答题者所用的时间是否超时、是否出现由于太难而未答的题目以及是否答题者中断答题；
⑥每答一道题目都会有相应的提示答题者是否做对错，如果错了还会有相应的正确答案。
程序缺点:
①统计答题时间时，把按按钮的时间都算上到答题时间上了；
②没有弄一个综合版本的，只能是在规定的选项题型中随机生成题目。弄一个综合版本对答题者可能更加好。（看了别人的程序后想到）
③答题完成后没有出答题的分数；
本次实验总结:
通过本次实验，不仅让我复习到了以前Java遗漏的知识，更重要的是明白到了一个人的想法是非常的局限的，只有通过和别人的交流和沟通后，才会知道自己的程序存在一些怎样的错误和不足，如何去进行改善。还有就是解决问题的方法和方式都有一定程度的改进，不会那么盲目，还可以培养一种当困难向你迎来时，能具有挑战接受它的精神。
