[Request] Introduction to concurrency in Java

[nipafx]

What is concurrent programming? Why do we do it? How do we do it safely? On the latter question, there's lots to explore:

• thread pools vs virtual threads (what to use when?)
• concurrent data structured (see [Request] Overview over concurrent data structures #9)
• locks, semaphores, etc.

Basically, everything in a java.util.concurrent.* package.

As there doesn't seem to be an article on the concept of threads, it might make sense to introduce that as well.

We have at least one article on virtual threads, now.
