Practice sleeping

It's not easy for first time play with Thread class. I spend some time on that five tasks, and after that I need some Thread.sleep(28_800_000).

Ok, so I understood all of these tasks, and was able to complete them all quite easily. Now I am worried. Usually when this happens, the next set of tasks will be impossible for me to complete without help, and ritualistic suicide seems the only recourse. Oh, CodeGym, how you like to lull us into a false sense of security.

The Big Ben exercise is quite stupid because it clearly says in the conditions that hours cannot be greater than 23 and minutes and seconds cannot be greater than 59 yet in the solution provided if user introduces 25, or 66 or 93 they are displayed as is. And I spent like a fool over an hour trying to find an algorithm that doesn't allow this when the solution doesn't even take this into consideration... Come on. CodeGym! Get your s**t together !

public static void main(String[] args) throws InterruptedException {
        Clock clock = new Clock("London", 23, 59, 57);
        Thread.sleep(4000);
        isStopped = true;
        Thread.sleep(1000);
    }

what is the purpose of the second Thread.sleep() call (line 5) in the exercises?

The Airport example is awesome. There are actually lots and lots of scenarios in which you need multithreading in real world airport and airtraffic control center systems. Pretty neat. :-)

Trick is not to overthink.

It must be hard to correct someone's code in real life.

DONE

The hardest part in these tasks is "Figure out what the program does", no kidding this is very tough for me
