1.因为要求换组员，上次作业和27号同学一起完成，这次作业与37号施少涛同学一起完成。http://www.cnblogs.com/shishaotao/

2.黑盒测试：点击确定->点击确定->（将非法字符清空）输入->

白盒测试：

3.单元测试：我们以数组的形式，数组先获取随机数存储进去，然后以数组的形式输出。因此，单元测试对数组进行初始化。最终输入的结果与算的结果相符合

4.总结：

预计用时半天，实际用时一天。

本次结对子编程非常有趣，又想到了一个功能，结束考试后，是否要再一次出题。还学会了单元测试，黑、白盒子测试技术。虽然我们把成品做出来了，过程中也有一些小争执。但是，我们主要的还是要学会怎么更好的运用JAVA编程，所以我们还要继续加油！~
