Uses of Package
java.util.concurrent

Packages that use java.util.concurrent

java.util.concurrent	Utility classes commonly useful in concurrent programming.
java.util.concurrent.locks	Interfaces and classes providing a framework for locking and waiting for conditions that is distinct from built-in synchronization and monitors.

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

AbstractExecutorService
Provides default implementation of ExecutorService execution methods.

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.

CompletionService
A service that decouples the production of new asynchronous tasks from the consumption of the results of completed tasks.

ConcurrentMap
A Map providing additional atomic putIfAbsent, remove, and replace methods.

Delayed
A mix-in style interface for marking objects that should be acted upon after a given delay.

ExecutionException
Exception thrown when attempting to retrieve the result of a task that aborted by throwing an exception.

Executor
An object that executes submitted Runnable tasks.

ExecutorService
An Executor that provides methods to manage termination and methods that can produce a Future for tracking progress of one or more asynchronous tasks.

Future
A Future represents the result of an asynchronous computation.

RejectedExecutionHandler
A handler for tasks that cannot be executed by a ThreadPoolExecutor.

ScheduledExecutorService
An ExecutorService that can schedule commands to run after a given delay, or to execute periodically.

ScheduledFuture
A delayed result-bearing action that can be cancelled.

ThreadFactory
An object that creates new threads on demand.

ThreadPoolExecutor
An ExecutorService that executes each submitted task using one of possibly several pooled threads, normally configured using Executors factory methods.

TimeoutException
Exception thrown when a blocking operation times out.

TimeUnit
A TimeUnit represents time durations at a given unit of granularity and provides utility methods to convert across units, and to perform timing and delay operations in these units.
