cookie，请问错在哪里应该怎么该改？谢谢。一般不耗尽智商我是不会提问的0.0

这是index.jsp
<%@ page language="java" import="java.util.*" contentType="text/html; charset=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>
 
    <title>cookie管理</title>
  </head>
  
  <body>
    
    <%
    String welcome="第一次访问";
    String[] info=new String[]{"","",""};
    Cookie[] cook=request.getCookies();
      if(cook!=null){
      for(int i=0;i<cook.length;i++){
          if(cook[i].getName().equals("mrCookInfo")){
          info=cook[i].getValue().split("#");
          welcome="欢迎回来！";
          }
      
      }
      }
     %>
     <%=info[0]+welcome %>
     <form action="show.jsp" method="post">
     <ul style="line=height:23px">
     <li>姓&nbsp;&nbsp;&nbsp;&nbsp;名：<input name="name" type="text" value="<%=info[0]%>"></li>
     <li>出生日期：<input name="birthday" type="text" value="<%=info[1] %>"></li>
     <li>邮箱地址：<input name="mail" type="text" value="<%=info[2]%>"></li>
     <li><input type="submit" value="提交"> 
  </body>
</html>

这是show.jsp

<%@ page language="java" import="java.util.*" contentType="text/html; charset=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>

<title>My JSP 'show.jsp' starting page</title>

</head>

<body>

String name=request.getParameter("name");

String birthday=request.getParameter("birthday");

String mail=request.getParameter("mail");

Cookie myCook=new Cookie("mrCookInfo",name+"#"+birthday+"#"+"mail");

myCook.setMaxAge(60*60*24*365);//设置cookie有效期

response.addCookie(myCook);

表单提交成功

</ul>

</body>

</html>

问题出在关于cookie管理知识点，show.jsp的代码运行错误提示是第22行

exception

org.apache.jasper.JasperException: An exception occurred processing JSP page /show.jsp at line 22

19:       String mail=request.getParameter("mail");
20:       Cookie myCook=new Cookie("mrCookInfo",name+"#"+birthday+"#"+"mail");
21:       myCook.setMaxAge(60*60*24*365);//璁剧疆cookie鏈夋晥鏈�
22:       response.addCookie(myCook);
23:      %>
