2 、教材P45  8题

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

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title></title>
</head>
<body bgcolor=cyan>
<jsp:include page="circle.jsp">
<jsp:param value="3" name="r"/>
</jsp:include>
<jsp:include page="ladder.jsp">
<jsp:param value="3" name="a"/>
<jsp:param value="5" name="b"/>
<jsp:param value="2" name="h"/>
</jsp:include>
</body>
</html>
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<body>
<%
String r=request.getParameter("r");
double R=Double.parseDouble(r);
double S=3.14*R*R;
out.print("圆的面积为"+S);
%>
</body>
</html>
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<body>
<%
 String a =request.getParameter("a");
String b =request.getParameter("b");
String h =request.getParameter("h");
double A =Double.parseDouble(a);
double B =Double.parseDouble(b);
double H =Double.parseDouble(h);
double s=(A+B)*H/2;
out.print("梯形面积为"+s);
%>
</body>
</html>

 

 

 

 3.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

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%="top.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"%>
<%="end.jsp" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<head>
</head>
<body>
<table border="1" bordercolor="yellow">           
        <tr> 
            <th colspan="2"><%@ include file="top.jsp" %></th>   
        </tr>
        <tr> 
            <th ><%@ include file="left.jsp" %></th>           
            <th ><%@ include file="right.jsp" %></th>   
        </tr>
        <tr> 
            <th colspan="2"><%@ include file="end.jsp" %></th>   
        </tr>
         
    </table>
</body>
</html>
