`HttpServletResponse` is a class in Java that is used to encapsulate HTTP-specific functionality in the response. It provides methods to set HTTP response headers, set the status code, and write the response content to the client.
For example, to set the content type of the response to "text/html" and write the response content, you can use the following code:
```java
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html><body>");
out.println("<h1>Hello World!</h1>");
out.println("</body></html>");
```
This will set the content type of the response to "text/html" and write the HTML code to the client's browser.

HttpServletResponse是Java Servlet API中的一个接口,表示服务器对客户端的响应。它提供了一组用于设置响应状态、添加头信息、设置响应体等的方法。开发人员可以通过实现这个接口来创建自定义的Servlet,并对客户端的请求进行响应。
HttpServletResponse response;
在创建servlet时,可以定义一个类型为HttpServletResponse的response变量。在servlet中,通过response对象可以实现对客户端的响应操作。具体操作包括重定向和设置响应头等。例如,可以使用response.sendRedirect()方法来进行重定向,使用response.setHeader()方法来设置响应头的属性。 同时,response对象还具有一些其他方法,如addHeader()、addIntHeader()、addDateHeader()等,用于向响应头中添加不同类型的属性。<span class="em">1</span><span class="em">2</span><span class="em">3</span><span class="em">4</span>
