Hi,

I'm studying for the OCP. From what I understand, a Deque has three methods that can remove an element from the left of a deque:
1. poll() - returns null for an empty list
2. remove() - throws an exception for an empty list
3. pop() - throws an exception for an empty list

Is there a difference between remove() and pop() when dealing with a Deque?

Thanks
