方法一：通过表达式
<%@ 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><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><%!String inputNiceNum(){String s = "";for(int i = 1;i<=9;i++){for(int j=1;j<=i;j++){s+=i+"*"+j+"="+(i*j)+" ";}s+="<br>";//换行}return s;}%><h1>九九乘法表</h1><%=inputNiceNum()%></body></html>
方法二：通过脚本
<body><%!//注意：这里抛出了一个异常是因为，系统怀疑//out.println(i+"*"+j+"="+(i*j)+" ");//可能会出现IO异常，所以不想捕获就要将其抛出////out 是一个内置对象，它的类型是 JspWriter void inputNiceNum(JspWriter out) throws Exception{for(int i=1;i<=9;i++){for(int j=1;j<=i;j++){out.println(i+"*"+j+"="+(i*j)+" ");}out.println("<br>");//换行}}%><h1>九九乘法表</h1><hr><% inputNiceNum(out);%></body>
