Hi Martin,

I checked this one...

I admit I had to study the Stack API first as I don't regularly use it 
nowadays ;-). You seem to be using the following replacements consistently:

Stack vs. ArrayDequeue

push(e) vs. addFirst(e)
add(0, e) vs. addLast(e)
isEmpty() / pop() vs. pollFirst()

...but then in push(URL[]), you use:

push(e) vs. push(e)

Deque.addFirst(e) is equivalent to Deque.push(e), but it would be nice 
to keep using the same method consistently in one class.
