JSP第二次作业

1.p39 实验2 显示当前时间，并输出上午(0-12)好,下午好(13-17),晚上好(18-23)

<%@ 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 'index.jsp' starting page</title>
  </head>
  
  <body>
  <%
  Date d=new Date();
  int h=d.getHours();
  int m=d.getMinutes();
  int s=d.getSeconds();
  out.print("当前时间为："+h+":"+m+":"+s+"<br>");
  if(h>=0&&h<=12){
  out.print("上午好");
  }else if(h>=13&&h<=17){
  out.print("下午好");
  }else{
  out.print("晚上好");
  }
     %>
  </body>
</html>

2. 使用声明方法,在页面调用该方法,判断2023是不是闰年

 

<%@ 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>是否闰年</title>
  </head>
  
  <body>
  <%!
        int show(int year){
            if(year%4==0&&year%400!=0||year%400==0){
                return 1;
            }else{
            return 0;
            }
        }
     %>
     <%
         if(show(2023)==1){
             out.println("是闰年");
         }else{
             out.println("不是润年");
         }
      %>
  </body>
</html>

3.表达式+程序段，循环输出5条hr,长度分别为100px-500px

<%@ 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>
    <title>循环</title>
  </head>
  
  <body>
    <%for(int i=100;i<600;i=i+100){ %>
           <hr width="<%=i%>">
       <%} %>
  </body>
</html>
