第二次JSP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 import="java.time.LocalTime"%> <%@page import="java.time.LocalDate"%> <%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html> <html> <head> <meta charset="ISO-8859-1"> <title>Insert title here</title> </head> <body> 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) <% LocalDate date = LocalDate.now(); LocalTime time = LocalTime.now(); %><br> <%=date.getYear() %> <%=date.getMonth() %> <%=date.getDayOfMonth() %> <%out.print("\n"); %><br> 小时为:<%int i =time.getHour(); out.print(i);%> 分钟为:<%=time.getMinute() %> 秒数为:<%=time.getSecond() %><br> 现在的问候: <%if(i<=12){ out.print("上午好"); }else if(i>12||i<=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
2023为:<%int year1 = 2023; %> <%if(year1%4==0){ out.print("闰年"); }else if(year1%4!=0){ out.print("平年"); }%> </body> </html>
3.表达式+程序段 循环输出5条hr,长度分别为100px-500px
<%@page import="java.time.LocalTime"%> <%@page import="java.time.LocalDate"%> <%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%> <!DOCTYPE html> <html> <head> <meta charset="ISO-8859-1"> <title>Insert title here</title> </head> <body> 3.表达式+程序段 循环输出5条hr,长度分别为100px-500px <% for(int i=100;i<=500;i=i+100){ %> <hr width="<%=i%>" ><br> <%} %> </body> </html>
4.在第一题上加Java注释,第二题加html注释,第三题加jsp注释
