四则运算网页版

小组成员：陈鹏李国帅

思路：使用jsp实现java代码与网页的连接，利用数组实现数据的传输。

源代码：

Ys.jsp

<p>
              有乘除
                <input type=checkbox name=cc1 value= true >
                  有负数 <input type=checkbox name=fu1 value= true >          
              多个数运算<input type=checkbox name=sys1 value= ture >
    
</p>

<p>
           最 小值： 
             <input  name="min1"  type="text"  class="input"  size="30" style="ime-mode:disabled"

           event.returnValue=false">   
          最大值： <input  name="max1"  type="text"  class="input"  size="30" style="ime-mode:disabled"

<p> 题数：

总结：这个作业做得不好，没有在特定的时间内做出来，今后要好好学习。
