Java LinkedBlockingDeque.poll() is a method in the Java LinkedBlockingDeque class that retrieves and removes the head of the deque, or returns null if the deque is empty. Unlike Java LinkedBlockingDeque.take(), poll() is non-blocking. Introduced in Java 2004 with Java 5, poll() is frequently used in scenarios where you need to safely access and remove elements from both ends of a deque in concurrent systems.
