public boolean isTerminated()

Returns true if all work has completed following shut down. Note that isTerminated is never true unless either shutdown or shutdownNow was called first.

Returns
TypeDescription
boolean

shutdown()

public void shutdown()

Initiates an orderly shutdown in which previously submitted work is finished, but no new work will be accepted. Invocation has no additional effect if already shut down.

This method does not wait for previously submitted work to complete execution. Use awaitTermination to do that.

shutdownNow()

public void shutdownNow()

Attempts to stop all actively executing work and halts the processing of waiting work.

This method does not wait for actively executing work to terminate. Use awaitTermination to do that.

There are no guarantees beyond best-effort attempts to stop processing actively executing work. For example, typical implementations will cancel via Thread.interrupt(), so any task that fails to respond to interrupts may never terminate.
