## Uses of Class
java.util.concurrent.TimeUnit

Packages that use TimeUnit
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.

Uses of TimeUnit in java.util.concurrent

Methods in java.util.concurrent that return TimeUnit
`static TimeUnit` | `TimeUnit.valueOf(String name)` Returns the enum constant of this type with the specified name.
`static TimeUnit[]` | `TimeUnit.values()` Returns an array containing the constants of this enum type, in the order they're declared.

Methods in java.util.concurrent with parameters of type TimeUnit
`int` | `CyclicBarrier.await(long timeout, TimeUnit unit)` Waits until all `parties` have invoked `await` on this barrier.
`boolean` | `CountDownLatch.await(long timeout, TimeUnit unit)` Causes the current thread to wait until the latch has counted down to zero, unless the thread is `interrupted`, or the specified waiting time elapses.
`boolean` | `ThreadPoolExecutor.awaitTermination(long timeout, TimeUnit unit)`
`boolean` | `ExecutorService.awaitTermination(long timeout, TimeUnit unit)` Blocks until all tasks have completed execution after a shutdown request, or the timeout occurs, or the current thread is interrupted, whichever happens first.
`long` | `TimeUnit.convert(long duration, TimeUnit unit)` Convert the given time duration in the given unit to this unit.
`V` | `Exchanger.exchange(V x, long timeout, TimeUnit unit)` Waits for another thread to arrive at this exchange point (unless it is `interrupted`, or the specified waiting time elapses), and then transfers the given object to it, receiving its object in return.
`V` | `FutureTask.get(long timeout, TimeUnit unit)`
`V` | `Future.get(long timeout, TimeUnit unit)` Waits if necessary for at most the given time for the computation to complete, and then retrieves its result, if available.
`long` | `Delayed.getDelay(TimeUnit unit)` Returns the remaining delay associated with this object, in the given time unit.
`long` | `ThreadPoolExecutor.getKeepAliveTime(TimeUnit unit)` Returns the thread keep-alive time, which is the amount of time which threads in excess of the core pool size may remain idle before being terminated.
`
`<T> List<Future<T>>`
` | `ExecutorService.invokeAll(Collection<Callable<T>> tasks, long timeout, TimeUnit unit)` Executes the given tasks, returning a list of Futures holding their status and results when all complete or the timeout expires, whichever happens first.
`
`<T> List<Future<T>>`
` | `AbstractExecutorService.invokeAll(Collection<Callable<T>> tasks, long timeout, TimeUnit unit)`
`
`<T> T`
` | `ExecutorService.invokeAny(Collection<Callable<T>> tasks, long timeout, TimeUnit unit)` Executes the given tasks, returning the result of one that has completed successfully (i.e., without throwing an exception), if any do before the given timeout elapses.
`
`<T> T`
` | `AbstractExecutorService.invokeAny(Collection<Callable<T>> tasks, long timeout, TimeUnit unit)`
`boolean` | `SynchronousQueue.offer(E o, long timeout, TimeUnit unit)` Inserts the specified element into this queue, waiting if necessary up to the specified wait time for another thread to receive it.
`boolean` | `PriorityBlockingQueue.offer(E o, long timeout, TimeUnit unit)` Inserts the specified element into this priority queue.
`boolean` | `LinkedBlockingQueue.offer(E o, long timeout, TimeUnit unit)` Inserts the specified element at the tail of this queue, waiting if necessary up to the specified wait time for space to become available.
`boolean` | `DelayQueue.offer(E o, long timeout, TimeUnit unit)` Inserts the specified element into this delay queue.
`boolean` | `BlockingQueue.offer(E o, long timeout, TimeUnit unit)` Inserts the specified element into this queue, waiting if necessary up to the specified wait time for space to become available.
`boolean` | `ArrayBlockingQueue.offer(E o, long timeout, TimeUnit unit)` Inserts the specified element at the tail of this queue, waiting if necessary up to the specified wait time for space to become available.
`E` | `SynchronousQueue.poll(long timeout, TimeUnit unit)` Retrieves and removes the head of this queue, waiting if necessary up to the specified wait time, for another thread to insert it.
`E` | `PriorityBlockingQueue.poll(long timeout, TimeUnit unit)`
`E` | `LinkedBlockingQueue.poll(long timeout, TimeUnit unit)`
`Future<V>` | `ExecutorCompletionService.poll(long timeout, TimeUnit unit)`
`E` | `DelayQueue.poll(long timeout, TimeUnit unit)` Retrieves and removes the head of this queue, waiting if necessary up to the specified wait time if no elements with an unexpired delay are present on this queue.
`Future<V>` | `CompletionService.poll(long timeout, TimeUnit unit)` Retrieves and removes the Future representing the next completed task, waiting if necessary up to the specified wait time if none are yet present.
`E` | `BlockingQueue.poll(long timeout, TimeUnit unit)` Retrieves and removes the head of this queue, waiting if necessary up to the specified wait time if no elements are present on this queue.
`E` | `ArrayBlockingQueue.poll(long timeout, TimeUnit unit)`
`
`<V> ScheduledFuture<V>`
` | `ScheduledThreadPoolExecutor.schedule(Callable<V> callable, long delay, TimeUnit unit)`
`
`<V> ScheduledFuture<V>`
` | `ScheduledExecutorService.schedule(Callable<V> callable, long delay, TimeUnit unit)` Creates and executes a ScheduledFuture that becomes enabled after the given delay.
`ScheduledFuture<?>` | `ScheduledThreadPoolExecutor.schedule(Runnable command, long delay, TimeUnit unit)`
`ScheduledFuture<?>` | `ScheduledExecutorService.schedule(Runnable command, long delay, TimeUnit unit)` Creates and executes a one-shot action that becomes enabled after the given delay.
`ScheduledFuture<?>` | `ScheduledThreadPoolExecutor.scheduleAtFixedRate(Runnable command, long initialDelay, long period, TimeUnit unit)`
`ScheduledFuture<?>` | `ScheduledExecutorService.scheduleAtFixedRate(Runnable command, long initialDelay, long period, TimeUnit unit)` Creates and executes a periodic action that becomes enabled first after the given initial delay, and subsequently with the given period; that is executions will commence after `initialDelay` then `initialDelay+period`, then `initialDelay + 2 * period`, and so on.
`ScheduledFuture<?>` | `ScheduledThreadPoolExecutor.scheduleWithFixedDelay(Runnable command, long initialDelay, long delay, TimeUnit unit)`
`ScheduledFuture<?>` | `ScheduledExecutorService.scheduleWithFixedDelay(Runnable command, long initialDelay, long delay, TimeUnit unit)` Creates and executes a periodic action that becomes enabled first after the given initial delay, and subsequently with the given delay between the termination of one execution and the commencement of the next.
`void` | `ThreadPoolExecutor.setKeepAliveTime(long time, TimeUnit unit)` Sets the time limit for which threads may remain idle before being terminated.
`boolean` | `Semaphore.tryAcquire(int permits, long timeout, TimeUnit unit)` Acquires the given number of permits from this semaphore, if all become available within the given waiting time and the current thread has not been `interrupted`.
`boolean` | `Semaphore.tryAcquire(long timeout, TimeUnit unit)` Acquires a permit from this semaphore, if one becomes available within the given waiting time and the current thread has not been `interrupted`.
