开发环境： Eclipse
题目方向： 一个能自动生成小学四则运算题目的程序，一个单机带用户界面（不是控制台）的程序。
题目要求：
- 生成题目，单个题目最多不能超过4个运算符，操作数小于100。
- 用户可以输入答案
- 若用户输入答案正确，则提示正确；若答案错误，则提示错误，并要提示正确答案是多少。
结对子用时： 3天3夜+1个下午
题目扩展方向：
- 程序设置了登录功能，新用户第一次使用程序时可以进行注册，旧用户使用程序时可以根据历史记录的信息而登录。
- 程序可以设置皮肤功能，更改界面的颜色。
- 用户可以设置做题的数目，答题结束后可以显示用户答题的对错数目并记录总分。
- 表达式里面可以进行计算负数的运算题目。
- 程序分别对加法、减法、乘法、除法设置了简单、适中和困难这3中程度的题目。
- 程序出错时，系统会反馈出错误的信息。

演示过程：
收获与感悟：
（ 在这一次结对子小项目中 ）
- 我主要充当领航员的作用，我的同伴充当着驾驶员的作用。
- 我的同伴主要是对程序进行编码，然后由我来后期调试。
- 一开始，我们两个分别独立完成一部分，后来发现，彼此的思想很难沟通且达成共识，于是，我们决定在课堂上好好珍惜面对面交流的时间，在课下利用QQ、微信、电话和远程操控的方式来进行深入探讨。
- 翅膀只剩一边是飞翔不起来的，尽管很努力的飞到半空，也不够双翅滑翔的轻松自如，所以合作真的很重要。在合作中，只有互相交流、交换思想，才会发现自己的优势和不足之处在哪里。因为有了时间的限制，所以有了无形的压力，所以我们更深的领悟到了时间观念的重要性。
- 我们在完成这次项目的时候，我们彼此改正缺点，彼此进步，得到的一点一滴的努力和进步，都会颇感欣慰。
- 由于有了同伴的监督，让我不敢偷懒，让我更认真的去查看和更正程序的不足，有了一个方向和目标，让我们更有追求。
- 当完成程序的所有测试后，很有成就感。
- 非常期待下一次的结对项目。
