Queue 的通用实现有 LinkedList 和 PriorityQueue,LinkedList 也是 Deque 的通用实现。(LinkedList 实现参见我的另外一篇博客:Java 集合框架2:List。) 对于Queue 的并发实现,在 java.util.concurrent 包中,主要有 LinkedBlockingQueue、ArrayBlockingQueue。 Deque 的通用实现还有 ArrayDeque,并发实现有 LinkedBlockingDeque。
内存一致性影响:与其他并发集合一样,在将对象放入 BlockingQueue的线程中的操作happen-before在另一个线程的 对BlockingQueue中访问或移除该元素的操作之前。 常见实现类有SynchronousQueue、ArrayBlockingQueue、DelayQueue、LinkedBlockingQueue、PriorityBlockingQueue等。 【3】 ArrayDeque 是一个基于数组的双端队列,和ArrayLi...
