项目进展
• 继续查看相关的书籍和资料：
- Java面向对象程序设计（第2版）北京邮电大学出版社：张桂珠 刘丽 陈爱国编写；
- Java程序设计实例教程[M]. 北京：冶金工业出版社：毕广吉编写；
- Java面向对象程序设计[M]. 北京：清华大学出版社：王保罗编写；
• 基本完成了项目的产品代码，代码如下：

•代码编写中主要用到的API如下：
setBackground(Color.WHITE)
time.start()
getKeyCode()
setSize(new Dimension( , ))
rand.nextInt( )
add()...
•将相关代码片段用IDEA进行了PUSH，截图如下：
成员贡献
• 20145210 姚思羽：继续进行代码的编写、框架的架构；
• 20145231 熊梓宏：继续进行博客的编写、代码托管、代码功能的完善；
• 两人共同完成：学习并调用新的API，对相关代码进行了理解总结，查找并学习了相关资料。
改进计划
本周在两人的共同努力下，我们完成了这个小项目的产品代码部分的编写，有了初步的运行结果，接下来的几周里，我们还将不断完善代码，利用测试代码改进我们的项目。
