本文介绍了Java并发包中LinkedBlockingDeque类的基本概念与使用方法。LinkedBlockingDeque实现了BlockingDeque接口，支持双端操作，并且在队列为空时会阻塞取元素的线程。文中通过示例展示了如何实例化LinkedBlockingDeque并进行基本操作。

The LinkedBlockingDeque class implements the BlockingDeque interface. Read the BlockingDeque text for more information about the interface.

The word Deque comes from the term "Double Ended Queue". A Deque is thus a queue where you can insert and remove elements from both ends of the queue.

The LinkedBlockingDeque is a Deque which will block if a thread attempts to take elements out of it while it is empty, regardless of what end the thread is attempting to take elements from.

Here is how to instantiate and use a LinkedBlockingDeque:

BlockingDeque<String> deque = new LinkedBlockingDeque<String>();

deque.addFirst("1");
deque.addLast("2");

String two = deque.takeLast();
String one = deque.takeFirst();
