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
