JSP生成九九乘法表的简单实例

一用表达式和脚本方式实现九九乘法表

<%@ page language="java" import="java.util.*" contentType="text/html; charset=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%>" rel="external nofollow" ><title>My JSP 'exercise.jsp' starting page</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0"><meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"><!--<link rel="stylesheet" type="text/css" href="styles.css" rel="external nofollow" >--></head><body><%!//返回九九乘法表对应的HTML代码，通过表达式来调用，在页面上显示String printMultiTable1(){ String s = ""; for(int i=1;i<=9;i++) { for(int j=1;j<=i;j++) {s+=i+"*"+j+"="+(i*j)+"&nbsp;&nbsp;&nbsp;&nbsp;"; } s+="<br>"; //追加换行标签 } return s;} //JSP内置out对象，使用脚本方式调用，打印九九乘法表void printMultiTable2(JspWriter out) throws Exception{for(int i=1;i<=9;i++){ for(int j=1;j<=i;j++) {out.println(i+"*"+j+"="+(i*j)+"&nbsp;&nbsp;&nbsp;&nbsp;"); } out.println("<br>"); //追加换行标签 }} %><h1>九九乘法表</h1><hr><%=printMultiTable1()%><br><% printMultiTable2(out);%><br> </body></html>

二运行效果
