They are not real threads. That is, the CPU is not context switching them but jvm running them in async.

Usually threads were also used for long running io but not cpu intensive tasks. It's recommended to use virtual threads for such scenarios now

Thanks!

As you can see, people can do it better. I put a limit on it because I didn't want an explanation of what threads are, just of the difference.

The post you replied to had four sentences. (But two paragraphs).

The explanation had two sentences :)

Edit: why are some commenters on HN so literal minded anyway? This is free form chat not code specs. You could have read "2 sentences" as "concise", you know...
