How do I talk to an Arduino using Java?

I need it for my CNC project. It seems this chunk of code works, but I don't know how to use it. See Stack Overflow question Control an Arduino with Java.

Take a look at page Arduino and Java. It talks about Java/Arduino serial communication.

However, to control an Arduino with Java, you have to program it to accept commands and send commands to it with Java. You can't directly control it with Java, because Arduino uses Processing, that is a C-like language.

I didn't downvote the question, but I think the reason it's getting downvoted is that you've already got a link to an answer, and yet you're asking the same question. It's almost as redundant-looking as posting a question that asks how to post a question.
