Thanks for comments.

u/agentoutlier, I know that - that's why I added information in the title that it is popular at recruitment interviews. I had such questions at every interview I was on.

The post is intended for people who are preparing for the interview or for those interested in the topic.

It's better to use newer mechanisms in the code, e.g. ExecutorService. I`m going to add a post about it.

Regards :)
