In this tutorial you will learn how to use setMaxAge() of Cookie class in java
setMaxAge() method sets the age of the cookie that how long it will be live. In other word we can say when a cookie will be expired.

Cookie cookie = new Cookie("CookieName","Cookie");

int age= cookie.getMaxAge();
out.println("Maximum time of cookie expiration is : "+age+" sec.");
}
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
