Answer / janet
Cookies are a mechanism that a servlet uses to have a
client hold a small amount of state-information associated
with the user.
a) create a cookie with the cookie constructor:
public Cookie(String name,String value)
b) A Servlet can send a cookie to the client by passing a
Cookie object to the addCookie() method of
HttpServletResponse:
public void HttpServletResponse.addCookie(Cookie
cookie)
c) A servlet retrieves cookie by calling the getCookies()
method of HttpServletRequest:
public Cookie[]HttpServletRequest.getCookie().

Cookies are small bit of textual information that are sent
from the webserver to the browser and sent back from the
browser to the server without changing the data later.
Cookies are helpful during e-commerce sessions when it will
be possible to recoginise a user during a session or it
helps in advertising as we can know the user preferences.
Cookies are created using:
Cookie c=new Cookie("name",value);
response.addCookie(c);
you can retrive the cookie value using:
request.getCookie() which returns a String giving the name
of the cookie and the value associated with the cookie.
