java.util.concurrent.LinkedBlockingQueue是一个底层为单向链表的,有界的,FIFO阻塞队列;访问和移除操作是在队头,添加操作在队尾进行,并且使用不同的锁进行保护。 在使用线程池时,如下两种方式创建的线程池,默认都是使用的LinkedBlockingQueue: Executors.newFixedThreadPool(3); Executors.newSingleThreadExecutor(); 1...

PriorityBlockingQueue<Integer> concurrentLinkedQueue =newPriorityBlockingQueue<Integer>(10,newComparator<Integer>() {@Overridepublicintcompare(Integer o1, Integer o2){returno2 - o1; } }); 应用场景 有任务要执行,可以对任务加一个优先级的权重,这样队列会识别出来,对该任务优先进行出队。
Removes a single instance of the specified element from this queue, if it is present. intsize() Returns the number of elements in this queue. Spliterator<E>spliterator() Returns aSpliteratorover the elements in this queue. Etake() Retrieves and removes the head of this queue, waiting if ...

if (front == back), then this is a case of a single element in the queue. After the deletion of this single element, queue become empty. So we need to set the empty queue condition before returning the value i.e.front = back = -1(Think!) ...
