How to use LinkedBlockingDeque in Java?

LinkedBlockingDeque is a FIFO (First-In-First-Out) double-ended queue in Java, which is implemented using a linked list.
Here are some common methods and uses of LinkedBlockingDeque:

1. Instantiate a LinkedBlockingDeque object:
2. Create a LinkedBlockingDeque object of type String and assign it to a variable called deque.
3. Add elements:
4. addFirst(E e): add an element to the front of the queue.
5. Add an element to the end of the queue.
6. Add the element to the head of the queue and return false if the queue is already full.
7. Add the element to the end of the queue, returning false if the queue is already full.
8. Retrieve and remove elements.
9. removeFirst(): Retrieve and remove the head element of the queue.
10. removeLast(): retrieve and eliminate the last element in the queue.
11. pollFirst(): Retrieve and remove the head element of the queue, returning null if the queue is empty.
12. pollLast(): Retrieve and remove the last element of the queue, returning null if the queue is empty.
13. Retrieve elements without removing them.
14. getFirst(): Retrieve the first element of the queue without removing it.
15. Get the last element of the queue without removing it.
16. peekFirst(): Retrieve but do not remove the first element of the queue, returning null if the queue is empty.
17. peekLast(): Retrieve, but do not remove, the last element of the queue. Return null if the queue is empty.
18. Blocking method:
19. Add an element to the head of the queue, blocking if the queue is already full.
20. Add the element to the end of the queue and wait if the queue is full.
21. takeFirst(): Retrieve and remove the head element from the queue, blocking if the queue is empty.
22. takeLast() method: retrieves and removes the last element of a queue, blocking if the queue is empty.

Note: LinkedBlockingDeque is thread-safe and can be operated on by multiple threads simultaneously.
