ArrayDeque Class

The ArrayDeque class in Java is a resizable array implementation of the Deque interface. It provides a flexible, efficient way to manage elements at both ends of the collection.

ArrayDeque can be used as both a stack (LIFO) and a queue (FIFO), making it a versatile tool for various applications. Unlike some other collections, it does not have capacity restrictions (unless memory is exhausted) and offers constant-time performance for insertion and removal at both ends.

  • Double-Ended Operations: Allows insertion and removal of elements at both the front and back of the deque.
