標籤：ima div coding orm IV html4 ping 閏年 建立
由用戶端輸入一個數，判斷是否為閏年
這是JSP頁面（給用戶端提供操作的頁面）
<%@ page language="java" contentType="text/html; charset=UTF-8"pageEncoding="UTF-8"%> <%@ page import="com.liaoyuanping.action.isLeap" %> --這是引用java代碼中的isLeap類方法<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>首頁</title></head><body><form action="Test_action.jsp">請輸入年份：<input type="text" name="txtYear" id="txtYear"><input type="submit" name="btnsub" id="btnsub" value="判斷"></form></body></html>
在同一個項目下的src下建立一個名為 com 的包，再建立一個isLeap類
這是Java代碼中的isLeap方法
package com.liaoyuanping.action;public class isLeap { private int year; public int getYear() { return year; } public void setYear(int year) { this.year = year; } public boolean isLeapYear(){ return(( year%100!=0 && year%4==0 || year%400==0)?true:false); }}
最後選擇整個項目右鍵選擇Run As --> Run on Server 運行，在瀏覽器頁面開啟
