3. 当阻塞队列因为消费者消费过慢或者生产者存放元素过快导致队列填满时无法容纳新元素时，生产者就会被阻塞，等待队列非满时继续存放元素。
4. 当消费者从队列中消费一个元素之后，队列就会通知生产者队列非满，生产者可以继续填充数据了。

总结一下：阻塞队列就说基于非空和非满两个条件实现生产者和消费者之间的交互，尽管这些交互流程和等待通知的机制实现非常复杂，好在 Doug Lea 的操刀之下已将阻塞队列的细节屏蔽，我们只需调用 `put`、`take`、`offfer`、`poll` 等 API 即可实现多线程之间的生产和消费。

这也使得阻塞队列在多线程开发中有着广泛的运用，最常见的例子无非是我们的线程池,从源码中我们就能看出当核心线程无法及时处理任务时，这些任务都会扔到 `workQueue` 中。
