scheduleAtFixedRate and scheduleWithFixedDelay

Now, please understand that scheduling jobs…generally occur in days, okay, but right now,…for the demonstration purposes,…I'm keeping the time unit as seconds.…Otherwise, I wouldn't be able to show you…how it is scheduled and how the run happens.…Okay.…There's one more thing that I have to do,…since I'm scheduling this job,…I have to run it periodically and I'm going to show you…at least two runs or three runs of this method call.…And in order to do that, I'll have to go back…to the cleaning scheduler and just comment on this call.…
