I need a Stack data structure for my use case. I should be able to push items into the data structure and I only want to retrieve the last item from the Stack. The JavaDoc for Stack says :

  
A more complete and consistent set of LIFO stack operations is
  provided by the Deque interface and its implementations, which should
  be used in preference to this class. For example:

Deque<Integer> stack = new ArrayDeque<>();

I definitely do not want synchronized behavior here as I will be using this datastructure local to a method . Apart from this why should I prefer Deque over Stack here ?

P.S: The javadoc from Deque says :

  
Deques can also be used as LIFO (Last-In-First-Out) stacks. This
  interface should be used in preference to the legacy Stack class.
