最近在学习慕课网的课程《java遇见HTML——JSP篇》，简单做些记录。

任务描述：分别使用表达式和脚本方式打印九九乘法表

代码如下：

<%@ 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%>"><title>My JSP 'index.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">--></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 = 0; i <= 9; i++) {for (int j = 1; j <= i; j++) {s += i + "*" + j + "=" + (i * j) + "    ";}s += "<br>";}return s;}//JSP内置out对象，试用脚本方式调用，打印九九乘法表void printMultiTable2(JspWriter out) throws Exception{String s = "";for (int i = 0; i <= 9; i++) {for (int j = 1; j <= i; j++) {out.println(i + "*" + j + "=" + (i * j) + "    ");}out.println("<br>");} }%><h1>九九乘法表</h1><!-- 表达式的方式输出 --><%=printMultiTable1()%> <!-- 注意脚本方式应该要以分号结束 --><% printMultiTable2(out);%> </body></html>
