Trying to do select/poll? There’s something like 4 different classes
and I don’t know how many methods involved.

 
There are several ways to do that in Java:
* java.nio
* Netty
* RxJava
* ...
 
All of them require a bit of documentation reading.
 
But so does the same problem in languages like C# and C.

The POSIX calls are quite straightforward
<https://manpages.debian.org/2/poll.2.en.html>.

And the typical Java application works at a higher level - it asks some
framework to listen at a given port and call some code to process
requests.

So does Python. Yet it can do it much more simply
<https://docs.python.org/3/library/select.html> -- even the asyncio
framework makes it easy to watch a file descriptor
