What is a Deque in Java?

Can you explain what a Deque is in Java?

Sure! A Deque, or double-ended queue, is a data structure that allows insertion and removal of elements from both ends.

What are the main operations I can perform on a Deque?

You can perform operations like addFirst, addLast, removeFirst, removeLast, and peek at both ends.

How does a Deque differ from a regular Queue?

Unlike a regular Queue, which follows FIFO (First In First Out), a Deque allows both FIFO and LIFO (Last In First Out) operations.

Can you give me an example of how to implement a Deque in Java?

Certainly! You can use the ArrayDeque class in Java. Here's a simple example: Deque<Integer> deque = new ArrayDeque<>();.
