<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>My JSP 'index.jsp' starting page</title> </head> <body> <% String r=request.getParameter("r"); double rr=Double.parseDouble(r); double area=3.14*rr*rr; out.print(area); %> </body> </html>
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>My JSP 'index.jsp' starting page</title> </head> <body> <% String t=request.getParameter("t"); double tt=Double.parseDouble(t); String b=request.getParameter("b"); double bb=Double.parseDouble(b); String h=request.getParameter("h"); double hh=Double.parseDouble(h); double area=(tt+bb)*hh/2; out.print(area); %> </body> </html>
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
