软件工程结对作业02

设计思想：

      写好java程序后，需要将程序嵌入网页中，编写jsp脚本文件，使用数组来实现java和jsp的交互；session标签，可以实现网页之间参数的传递。

源程序代码(java)：

编程总结：

      我们已经写好了java程序，功能也基本实现，但是在程序嵌入到网页过程中，我们遇到了很多困难，由于我们的程序并没有分模块去写，所以在调用时出现了很多困难，正确结果及用户输入的结果也没有保存在数组里面，所以在网页中不能传递数组值进行判断；后我们查阅了资料，借鉴阅读了一些已完成的程序，但是我们的程序并没有修改正确，嵌入不正确，没有完成后面的功能。
