- 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.
  BrokenBarrierException Exception thrown when a thread tries to wait upon a barrier that is in a broken state, or which enters the broken state while the thread is waiting.
  Callable A task that returns a result and may throw an exception.
  CompletableFuture A `Future` that may be explicitly completed (setting its value and status), and may be used as a `CompletionStage`, supporting dependent functions and actions that trigger upon its completion.
  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.
  ConcurrentHashMap.KeySetView A view of a ConcurrentHashMap as a `Set` of keys, in which additions may optionally be enabled by mapping to a common value.
  ConcurrentMap A `Map` providing thread safety and atomicity guarantees.
  ConcurrentNavigableMap A `ConcurrentMap` supporting `NavigableMap` operations, and recursively so for its navigable sub-maps.
