首先使用JSP声明声明一个函数用于得到九九乘法表的内容

<%!    String printMultiTable() {        String s = "";        for (int i = 1; i < 10; i ++) {            for (int j = 1; j <= i; j ++)                 s += " " + i + " * " + j + " = " + (i * j) + " ";            s += "
";                }        return s;    }%>

然后在JSP脚本中使用它：

<%=printMultiTable() %>

完整的代码：

<%@ page language="java" contentType="text/html; charset=utf-8"    pageEncoding="utf-8"%>
      <%!    String printMultiTable() {        String s = "";        for (int i = 1; i < 10; i ++) {            for (int j = 1; j <= i; j ++)                 s += " " + i + " * " + j + " = " + (i * j) + " ";            s += "
";                }        return s;    }%>九九乘法表：
<%=printMultiTable() %>

效果：
