1.设计思路
1）设计网页
（1）.在网页中可以计算四则运算和两个数的加减法，并可以判断结果是否正确，先设置一个网页first.jsp判断是否进行四则运算，将值传到second.jsp,进行选择范围界面，如果不进行四则运算，传到NewFile.jsp界面进行两个数的计算选择界面。两个页面都将选择的值传到NewFile1.jsp界面进行计算，将结果在NewFile2.jsp界面进行判断结果；
（2）.网页中单选框放在表单进行传值，在页面中共享的值用session.getAttribute进行传值，并用session设置一个计数器，可实现循环计算并输出计算个数；
2）计算
(1) .用jsp脚本将原四则运算的java文件调用进来，进行四则和两个数计算和判断问题，
（2）.四则运算：用栈实现stack1用来存放数，stack2存放符号的，
