What are the different types of queues in Java?

In Java, there are several types of queues, including LinkedList, PriorityQueue, and ArrayDeque. Each has its own use cases.

Can you explain how a PriorityQueue works?

A PriorityQueue in Java orders elements based on their natural ordering or a provided comparator, allowing for efficient retrieval of the highest or lowest priority element.

What is the difference between LinkedList and ArrayDeque?

LinkedList allows for constant-time insertions and deletions, while ArrayDeque offers better performance for stack and queue operations due to its dynamic array structure.

When should I use a BlockingQueue?

A BlockingQueue is useful in concurrent programming when you need to manage access to a shared resource, allowing threads to wait for elements to become available.
