- - ### Uses of BlockingQueue in java.util.concurrent

    Subinterfaces of BlockingQueue in java.util.concurrent
    Modifier and Type | Interface and Description
    --- | ---
    `interface` | `BlockingDeque<E>` A `Deque` that additionally supports blocking operations that wait for the deque to become non-empty when retrieving an element, and wait for space to become available in the deque when storing an element.

    Classes in java.util.concurrent that implement BlockingQueue
    Modifier and Type | Class and Description
    --- | ---
    `class` | `ArrayBlockingQueue<E>` A bounded blocking queue backed by an array.
    `class` | `DelayQueue<E extends Delayed>` An unbounded blocking queue of `Delayed` elements, in which an element can only be taken when its delay has expired.
    `class` | `LinkedBlockingDeque<E>` An optionally-bounded blocking deque based on linked nodes.
    `class` | `LinkedBlockingQueue<E>` An optionally-bounded blocking queue based on linked nodes.
    `class` | `PriorityBlockingQueue<E>` An unbounded blocking queue that uses the same ordering rules as class `PriorityQueue` and supplies blocking retrieval operations.
    `class` | `SynchronousQueue<E>` A blocking queue in which each insert operation must wait for a corresponding remove operation by another thread, and vice versa.

    Methods in java.util.concurrent that return BlockingQueue
    Modifier and Type | Method and Description
    --- | ---
    `BlockingQueue<Runnable>` | ThreadPoolExecutor.`getQueue()` Returns the task queue used by this executor.
    `BlockingQueue<Runnable>` | ScheduledThreadPoolExecutor.`getQueue()` Returns the task queue used by this executor.

    Constructors in java.util.concurrent with parameters of type BlockingQueue
    Constructor and Description
    `ExecutorCompletionService(Executor executor, BlockingQueue<Future<V>> completionQueue)` Creates an ExecutorCompletionService using the supplied executor for base task execution and the supplied queue as its completion queue.
    `ThreadPoolExecutor(int corePoolSize, int maximumPoolSize, long keepAliveTime, TimeUnit unit, BlockingQueue<Runnable> workQueue)` Creates a new `ThreadPoolExecutor` with the given initial parameters and default thread factory and rejected execution handler.
    `ThreadPoolExecutor(int corePoolSize, int maximumPoolSize, long keepAliveTime, TimeUnit unit, BlockingQueue<Runnable> workQueue, RejectedExecutionHandler handler)` Creates a new `ThreadPoolExecutor` with the given initial parameters and default thread factory.
    `ThreadPoolExecutor(int corePoolSize, int maximumPoolSize, long keepAliveTime, TimeUnit unit, BlockingQueue<Runnable> workQueue, ThreadFactory threadFactory)` Creates a new `ThreadPoolExecutor` with the given initial parameters and default rejected execution handler.
    `ThreadPoolExecutor(int corePoolSize, int maximumPoolSize, long keepAliveTime, TimeUnit unit, BlockingQueue<Runnable> workQueue, ThreadFactory threadFactory, RejectedExecutionHandler handler)` Creates a new `ThreadPoolExecutor` with the given initial parameters.
