实验目的及要求实验要求：1.掌握JavaBean的编写方法。
2.掌握调试JavaBean
3.学习使用JavaBean
实验环境
硬件平台：PC机
软件平台：Windows 操作系统
编程环境：Eclipse
实验内容与实验过程实验内容：
使用Bean计算矩形面积（长：2，宽：4）
1.创建求矩形面积的JavaBean。JavaBean的名字为：MyRectangle。创建的源文件为MyRectangle.java
package com.website;
public class MyRectangle implements java.io.Serializable
{
private int chang = 4;
private int kuan = 2;
private int juxing = chang * kuan;
public MyRectangle() {
}
public int getJuxing(){
return juxing;
}
public void setJuxing(int juxing){
this.juxing = juxing;
}
}
2. 创建ch5_1.jsp文件。运行ch5_1.jsp如下图得出矩形面积。

<%@ page import="java.io.*,java.util.*" %>
<%@ page import="com.website.MyRectangle" %>
