What is the Java BlockingDeque interface used for?

The Java BlockingDeque interface is used for creating a double-ended queue that supports blocking operations. It extends the BlockingQueue interface and provides additional methods for adding and removing elements from both ends of the queue. The blocking operations allow threads to wait until the queue is not full or not empty before performing the operation, making it useful for implementing producer-consumer scenarios and other concurrent applications.
