半径是：<%=r%>
<br>圆的面积是：<%=getArea(r) %>
</body>
<%@page contentType="text/html;charset=utf-8"%>
<%! public String getArea(double a,double b,double c)
{

String sideB=request.getParameter("sideB");
String sideC=request.getParameter("sideC");
double a=Double.parseDouble(sideA);

%>
<br><br>我是被加载的文件，负责计算梯形的面积<br>
给我传递的上底、下底、高是：<%=sideA%> <%=sideB %> <%=sideC %>
<br>梯形的面积是：<%=getArea(a,b,c) %>
