STACK

Extends the Vector to have a stack model with LIFO (Last In First Out) functionality.

EXAMPLE FOR STACK:

Utilizing push(), pop(), peek() in a frame of condition with empty() provides the functionality of a stack structure.

However, by inheriting Vector, it is not data-safe (data can be read from other positions and toString() shows the push() order instead of pop order) nor thread-safe, and has no extended functionality for stack data structure. Use ArrayDeque class (implementing Deque interface) instead.
