任务二、教材P45  8题

提示：圆形面积需要一个param  梯形面积需要3个param,可以参考教材例2-11

 

  <body>
    <%!double getarea(double r){
           double area=3.14*r*r;
           return area;
   } %>
   <%
   String r=request.getParameter("r");
   double r1=Double.parseDouble(r);
   double area=getarea(r1);
   out.print("圆形的半径是"+r+",圆形的面积："+area);
    %>
  </body>

 

 <body>
    <%!double getarea(double r){
           double area=3.14*r*r;
           return area;
   } %>
   <%
   String r=request.getParameter("r");
   double r1=Double.parseDouble(r);
   double area=getarea(r1);
   out.print("圆形的半径是"+r+",圆形的面积："+area);
    %>
  </body>
<body>
     <%!double getarea(double s,double x,double g){
           double area=(s+x)*g/2;
           return area;
   } %>
   <%
   String string=request.getParameter("s");
   double s1=Double.parseDouble(string);
   string=request.getParameter("x");
   double x1=Double.parseDouble(string);
   string=request.getParameter("g");
   double g1=Double.parseDouble(string);
   double area=getarea(s1, x1, g1);
   
   out.print("梯形的上底是"+s1+"下底是"+x1+"高是"+g1+"面积是"+area);
    %>
   
  </body>
