Answer

So well why should threads sleep 1000000000 milliseconds. In that case your thread does its tasks every 1000000 seconds.

1000000000 ms => 1000000 sec => 16666 min => 277 hour

So your thread does its task every 277 hours. The param of sleep is millisecond so put st like 1000(1 second) or something like that which is a lot shorter. If this wasn’t solution let me know.
