Java Deque is an interface in Java that extends the Java Queue interface and allows elements to be added or removed from both ends of the queue. It provides additional methods like Java addFirst() and Java addLast() for more flexible queue manipulation. Introduced in Java 2004 with Java 5, Deque is part of Java's Java Collections Framework and is used in scenarios where elements need to be processed in both FIFO and LIFO orders.
