特殊线性表--队列在JAVA中的实现

Cookie userCookie = new Cookie("password", pwd);
//设定有效时间  以秒(s)为单位
userCookie.setMaxAge(60);
//设置Cookie路径和域名
userCookie.setPath("/emd-plus") ;
//		      userCookie.setDomain(".emd-plus") ;  //域名要以“.”开头
response.addCookie(userCookie);

Cookie cookies[] = request.getCookies();
String password = "";
if(null != cookies){
for(Cookie c :cookies){
String cName = c.getName();
String cValue = c.getValue();
if("password".equals(cName)){
password = cValue;
}
}
}
