Class	Description
AbstractExecutorService	The ExecutorService methods that need nothing but execute: a subclass provides execution and the life cycle, and gets submit, invokeAll and invokeAny from here.
Callable<V>	A task that answers a result and may throw.
CancellationException	Thrown by Future.get() when the work was cancelled before it ran.
CompletableFuture<T>	java.util.concurrent.CompletableFuture for the Codename One runtime.
CompletionException	java.util.concurrent.CompletionException: a stage failed, or the one it depended on did; the cause is the original exception.
CompletionStage<T>	java.util.concurrent.CompletionStage: one step of a computation that others can be attached to.
ConcurrentHashMap<K,V>	java.util.concurrent.ConcurrentHashMap for the Codename One runtime, over a HashMap.
ConcurrentHashMap.KeySetView<K,V>	java.util.concurrent.ConcurrentHashMap.KeySetView: the keys of a map as a set.
ConcurrentMap<K,V>	A map whose compound operations are atomic.
CopyOnWriteArrayList<E>	java.util.concurrent.CopyOnWriteArrayList for the Codename One runtime.
CopyOnWriteArraySet<E>	java.util.concurrent.CopyOnWriteArraySet for the Codename One runtime: a set kept in a CopyOnWriteArrayList, in the order its elements were added.
CountDownLatch	java.util.concurrent.CountDownLatch: threads wait until a count reaches zero.
Delayed	Something that is due after a delay, ordered by when it is due.
ExecutionException	Thrown by Future.get() when the work failed; the cause is what it threw.
Executor	Runs submitted tasks, on a thread of its choosing.
Executors	Factories for the executor services.
ExecutorService	An Executor that answers a Future for a submitted task and can be shut down.
Future<V>	The result of work that finishes later -- on the backend, what an @Async method returns, completed when its body has run on its executor.
FutureTask<V>	A cancellable computation whose result is read through Future.
RejectedExecutionException	Thrown by an Executor that does not accept a task, typically because it has been shut down.
RunnableFuture<V>	A Future that is also the task computing it: running it completes it.
ScheduledExecutorService	java.util.concurrent.ScheduledExecutorService: an executor that also runs work after a delay, or again and again.
ScheduledFuture<V>	java.util.concurrent.ScheduledFuture: the result of work an executor was asked to run later.
ThreadFactory	Makes the threads an executor runs its tasks on.
ThreadLocalRandom
TimeoutException	Thrown by Future.get(long, TimeUnit) when the work has not finished in time.
TimeUnit	Compile-time API for time units.
