Deque Interface

Deque interfaces are fascinating structures that provide a lot of flexibility in how we manage data. Think of a deque, or double-ended queue, as a versatile line of people at a coffee shop. You can add or remove customers from both ends of the line.

This ability to operate from both the front and back of the queue opens up a world of possibilities.

In this chapter, we’ll dive deep into the Deque interface in Java, discussing how it fits into the Collections Framework and showcasing practical applications and nuances that you'll find useful in real-world scenarios.
