### Uses of Executor in java.util.concurrent

Subinterfaces of Executor in java.util.concurrent
`interface` `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.
`interface` `ScheduledExecutorService` An `ExecutorService` that can schedule commands to run after a given delay, or to execute periodically.

Classes in java.util.concurrent that implement Executor
`class` `AbstractExecutorService` Provides default implementations of `ExecutorService` execution methods.
`class` `ForkJoinPool` An `ExecutorService` for running `ForkJoinTask`s.
`class` `ScheduledThreadPoolExecutor` A `ThreadPoolExecutor` that can additionally schedule commands to run after a given delay, or to execute periodically.
`class` `ThreadPoolExecutor` An `ExecutorService` that executes each submitted task using one of possibly several pooled threads, normally configured using `Executors` factory methods.

Methods in java.util.concurrent that return Executor
`Executor` CompletableFuture.`defaultExecutor()` Returns the default Executor used for async methods that do not specify an Executor.
`static Executor` CompletableFuture.`delayedExecutor​(long delay, TimeUnit unit)` Returns a new Executor that submits a task to the default executor after the given delay (or no delay if non-positive).
