![ArrayBlockingQueue 类图](https://oss.javaguide.cn/github/javaguide/java/collection/arrayblockingqueue-class-diagram.png)

从图中我们可以看出,`ArrayBlockingQueue` 继承了阻塞队列 `BlockingQueue` 这个接口,不难猜出通过继承 `BlockingQueue` 这个接口之后,`ArrayBlockingQueue` 就拥有了阻塞队列那些常见的操作行为。
从图中我们可以看出,`ArrayBlockingQueue` 实现了阻塞队列 `BlockingQueue` 这个接口,不难猜出通过实现 `BlockingQueue` 这个接口之后,`ArrayBlockingQueue` 就拥有了阻塞队列那些常见的操作行为。

同时, `ArrayBlockingQueue` 还继承了 `AbstractQueue` 这个抽象类,这个继承了 `AbstractCollection` 和 `Queue` 的抽象类,从抽象类的特定和语义我们也可以猜出,这个继承关系使得 `ArrayBlockingQueue` 拥有了队列的常见操作。

所以我们是否可以得出这样一个结论,通过继承 `AbstractQueue` 获得队列所有的操作模板,其实现的入队和出队操作的整体框架。然后 `ArrayBlockingQueue` 通过继承 `BlockingQueue` 获取到阻塞队列的常见操作并将这些操作实现,填充到 `AbstractQueue` 模板方法的细节中,由此 `ArrayBlockingQueue` 成为一个完整的阻塞队列。

为了印证这一点,我们到源码中一探究竟。首先我们先来看看 `AbstractQueue`,从类的继承关系我们可以大致得出,它通过 `AbstractCollection` 获得了集合的常见操作方法,然后通过 `Queue` 接口获得了队列的特性。
