Classes in java.util.concurrent used by java.util.concurrent

Class and Description
AbstractExecutorService Provides default implementations of ExecutorService execution methods.
BlockingDeque 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.
BlockingQueue A Queue that additionally supports operations that wait for the queue to become non-empty when retrieving an element, and wait for space to become available in the queue when storing an element.

CompletionService A service that decouples the production of new asynchronous tasks from the consumption of the results of completed tasks.
CompletionStage A stage of a possibly asynchronous computation, that performs an action or computes a value when another CompletionStage completes.
