Answer
Throws NoSuchElementException. Frame the concept in practical terms so you can explain it during interview discussion.
If you call the remove() method on an empty Queue, it throws a NoSuchElementException. To avoid this exception, you can use poll(), which returns null when the queue is empty. This is important to handle gracefully in applications like message processing services, where you want to avoid crashes due to empty queues.
