Cookies. Page that checks cookies gives error if there are no cookies.

Question

Hi All,
I got the code that checks for cookie names :
Cookie[] cookies = request.getCookies();
out.println("there are " + cookies.length + " cookies<br>");
for(int i = 0; i < cookies.length; i++)
     out.println("<li>" + cookies.getName() + ": " + cookies[i].getValue());
     if (cookies[0].getName().equals("user")) {
          String someString = cookies[0].getName();
          out.println("<p><p>" + someString);
But when there are no cookies, this page gives an error. So first there
should be some code that checks if there are cookies and if so then
check to see what cookies there are.
But how would I do this?
It allready gives an error at :
Cookie[] cookies = request.getCookies();
Thanks for any help!!

Cookie[] cookies = request.getCookies();
if (cookies != null) {
    out.println("there are " + cookies.length + " cookies<br>");
    for(int i = 0; i < cookies.length; i++)
     out.println("<li>" + cookies.getName() + ": " + cookies[i].getValue());
     if (cookies[0].getName().equals("user")) {
          String someString = cookies[0].getName();
          out.println("<p><p>" + someString);
} else {
out.println("there are no cookies ");
