心得体会：

吴旭涛

通过四则运算的编码，编程Java界面的时，通过jdk的插件

，对按钮、输入框都有了一定的掌握，对于结对合作的方面，

加深了团队合作的重要性，对计算机编程开发、执行、

应用软件等方面有重大的意义

王宏财：

在编码四则运算过程中，

初步了解了Java界面和C语言相结合的特点，

对于随机生成四则运算方面遇到不晓得问题

，统计运行时间、错题、对题、对面板换肤等方面有点不足，

还有待进步。通过这次结对合作，

充分体会到团队合作的重要性，

以后会好好对待每一个合作机会

优点：

1.按开始按键就开始计时，按交卷键就暂停即总时间

2.有计算答对的个数，答错的个数和总分

3.能换多种皮肤

缺点：

1.计时器到了120秒不会自动交卷

2.再按开始，答题区不会清空

3.没写哪道题对，哪道题错
