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

任务三、
1.应用表格对页面进行布局（可以借助于Dreamweaver 制作页面框架)，如下图所示。表格中显示的文件内容为使用include指令引入相应的JSP文件（JSP文件的内容不限)。
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index1.jsp' starting page</title>
</head>
<body >
<table border="1" width="600" align="center" bgcolor="red">
<tr align="center"><td colspan="2"><%@include file="top.jsp" %></td></tr>
<tr align="center"><td><%@include file="left.jsp" %></td><td align="center"><%@include file="right.jsp" %></td></tr>
<tr align="center"><td colspan="2"><%@include file="bottom.jsp" %></td></tr>
</table>
</body>
</html>
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%="bottom.jsp"%>
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%="left.jsp"%>
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%="right.jsp"%>
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%="top.jsp"%>
任务四
编写一个JSP文件，在该文件中，应用Math.round(Math.random()*10)生成[0,10]之间的随机整数，然后根据生成的是偶数还是奇数，应用<jsp:forward>动作标记分别跳转到对应的偶数页面和奇数页面。
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>

</head>
<body>
<%
int i = (int) (Math.random() * 10 + 1);
if (i % 2 == 0) {
%>
<jsp:forward page="ou.jsp">
<jsp:param value="<%=i %>" name="i" />
</jsp:forward>
<%
} else {
%>
<jsp:forward page="ji.jsp">

</jsp:forward>
<%
}
%>

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
