All Implemented Interfaces:
Serializable, Cloneable, Iterable<E>, Collection<E>, Deque<E>, List<E>, Queue<E>, MyStack<E>
public class LinkedListStackImpl<E> extends LinkedList<E> implements MyStack<E>
A simple delegate to a LinkedList. Unlike java.util.Stack, this implementation is non-synchronized to improve performance.

It performs slower than the ArrayStackImpl version.

There is no maximum capacity which is enforced, nor is there any checks if pop() is executed on an empty stack.
