Uses of Interface
java.util.concurrent.Future
Packages that use Future
java.util.concurrent
Utility classes commonly useful in concurrent programming.
Uses of Future in java.util.concurrent
Subinterfaces of Future in java.util.concurrent
interface
RunnableFuture<V>
A Future that is Runnable.
interface
RunnableScheduledFuture<V>
A ScheduledFuture that is Runnable.
interface
ScheduledFuture<V>
A delayed result-bearing action that can be cancelled.
Classes in java.util.concurrent that implement Future
class
CompletableFuture<T>
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.
abstract class
CountedCompleter<T>
A ForkJoinTask with a completion action performed when triggered and there are no remaining pending actions.
abstract class
ForkJoinTask<V>
Abstract base class for tasks that run within a ForkJoinPool.
class
FutureTask<V>
A cancellable asynchronous computation.
abstract class
RecursiveAction
A recursive resultless ForkJoinTask.
abstract class
RecursiveTask<V>
A recursive result-bearing ForkJoinTask.
Methods in java.util.concurrent that return Future
<T> Future<T>
AbstractExecutorService.submit(Callable<T> task)
Submits a value-returning task for execution and returns a Future representing the pending results of the task.
Future<?>
AbstractExecutorService.submit(Runnable task)
Submits a Runnable task for execution and returns a Future representing that task.
<T> Future<T>
AbstractExecutorService.submit(Runnable task, T result)
Submits a Runnable task for execution and returns a Future representing that task.
Future<V>
CompletionService.poll()
Retrieves and removes the Future representing the next completed task, or null if none are present.
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.
Future<V>
CompletionService.submit(Callable<V> task)
Submits a value-returning task for execution and returns a Future representing the pending results of the task.
Future<V>
CompletionService.submit(Runnable task, V result)
Submits a Runnable task for execution and returns a Future representing that task.
Future<V>
CompletionService.take()
Retrieves and removes the Future representing the next completed task, waiting if none are yet present.
Future<V>
ExecutorCompletionService.poll()
Retrieves and removes the Future representing the next completed task, or null if none are present.
Future<V>
ExecutorCompletionService.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.
Future<V>
ExecutorCompletionService.submit(Callable<V> task)
Submits a value-returning task for execution and returns a Future representing the pending results of the task.
Future<V>
ExecutorCompletionService.submit(Runnable task, V result)
Submits a Runnable task for execution and returns a Future representing that task.
Future<V>
ExecutorCompletionService.take()
Retrieves and removes the Future representing the next completed task, waiting if none are yet present.
<T> Future<T>
ExecutorService.submit(Callable<T> task)

ExecutorService.submit(Runnable task, T result)
Submits a Runnable task for execution and returns a Future representing that task.
<T> Future<T>
ScheduledThreadPoolExecutor.submit(Callable<T> task)
Submits a value-returning task for execution and returns a Future representing the pending results of the task.
Future<?>
ScheduledThreadPoolExecutor.submit(Runnable task)
Submits a Runnable task for execution and returns a Future representing that task.
<T> Future<T>
ScheduledThreadPoolExecutor.submit(Runnable task, T result)
Submits a Runnable task for execution and returns a Future representing that task.
Methods in java.util.concurrent that return types with arguments of type Future
