最近在学习慕课网的课程《java遇见HTML——JSP篇》，简单做些记录。
课程网址为：http://www.imooc.com/learn/166
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>
