18:12 doesn't make any sense to me. You just created a new completableFuture and it is not linked with the single thread executor you just created and submitted, The returned object from the STR should be assigned to completableFuture correct?

[@PrashantSharmaOfficial]

Is it necessary to link CompletableFuture with Single Thread Executor? This should answer your first question.
To your second one - Yes, we can return an object/null but I tried to show a simple example which even beginners can understand.
