@rolfl Why would you want that?
@rolfl Couldn't have described it better myself. Although my time counter is "only" 917 hours.
 
I want to feed speed modules in to beacons, but only turn them on when demanded.... otherwise beacons consume electricity for no output.
Trying to get dense beacons while using power cables with circuit-controlled power switch, is painful.
 
@rolfl Aaaah.... that'd be a really good feature-request.

I wonder if SE platform has some kind of bot detecting mechanisms.
Am I paranoid?

If your code produces the correct output but it appears to be too slow, you should post your question on Code Review, not StackOverflow. I'd start with replacing the ArrayList<Long> with long[] and maybe Scanner with a faster input method — Fureeish 56 secs ago

@Antoniossss yes I know stream.foreach does the same thing, for a straightforward situation it works very easily and I know it would also work and should work, but transforming this code looks a little bit difficult for me.
