以下是完整代码：

<%@ page language="java" import="java.util.*,java.io.*" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<%

response.setContentType("text/html:charset=rtf-8");//设置响应的MIMI类型

out.println("<h1>response内置对象</h1>");

out.println("<hr>");

PrintWriter outer=response.getWriter();//获得输出流对象

outer.println("大家好，我是response对象生成的输出流outer对象。");

%>

PrintWriter outer=response.getWriter();这里为何要用response.getWriter()而不用PrintWriter.getWriter()呢
