怎么在java中使用cookie

<%--客户端添加Cookie信息--%>
<%@ page language="java" pageEncoding="UTF-8"%>
             
        
     <%  response.addCookie(new Cookie("Cookie1","firstCookie"));  response.addCookie(new Cookie("Cookie2","secondCookie"));   %>   getcookie   
 
<%--request获取客户端Cookie信息,在工程下新建JSP_getCookie.jsp--%>
<%@ page language="java" pageEncoding="UTF-8"%>
 
             
         
       <%  Cookie cookie[]=request.getCookies();  String Cookiename1="";  String Cookiename2="";  if(cookie!=null){  for(int i=0;i   <%   out.println("Cookie1的值:"+Cookiename1);   } %>   
   <%   out.println("Cookie2的值:"+Cookiename2);    %>
  

request对象获取cookie对象，get,set属性
