Cookies

[Fes D Gaur]

I'm setting a cookie using:
Cookie cook = new Cookie("Key","This Value");

Right now I have to do the following to retrieve the value of the Cookie:

PrintWriter out = resp.getWriter();
Cookie cookie[] = req.getKookies();
out.println(cookie.length);
for(int i=0;i<cookie.length;i++)
out.println(cookie[i].getValue());

How do I retrieve the value of the Cookie using the key or name of the cookie?

Thanks,
Faisal

Whats wrong with using the Cookie getName() method?

[Fes D Gaur]

Using the Cookie getName() is fine. But do I have to iterate through all the cookies and use an if equals to cookie name logic to get the cookie that I want? Or can I use the getName() method to get the value of the cookie that I want directly?

Could you please write a little piece of code that retrieves a cookie by using the Cookie's name.

Thanks,
Faisal

/**
 * @return the value for the requested cookie or null if no cookies match the given name.
 */
public String getCookieValue(Cookies[] cookies, String name){
    for(int i = 0; i < cookies.length; i++){
        if(cookies[i].getName().equals(name))
            return cookies[i].getValue();
    }
    return null;
}

I didn't test it but you should get the idea.
