该作业主要在两个网页上进行展示，分别为001.jsp和002.jsp。001.jsp有一个表单字段:number，002.jsp接受这个表单数据并进行判断。
此为001.jsp的代码段
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<%@ page contentType="text/html;charset=gb2312" %>
<%!int Num = 0; %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
