Java on Fedora - a first program

I am currently running Fedora 38 on my x86_64 desktop. I just installed java and javac (version 20) from the standard package set (or at least I think I did), and now want to try them out on the simplest possible thing. So I create the file "hello.java" with the following content: 
// Tom Trebisky  6-19-2023

class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}
I "compile" this with: 
javac hello.java
This produces the file "HelloWorld.class", I run it via: 
java HelloWorld
Hello, World!
It looks like I am on the air in a basic way.
Have any comments? Questions? Drop me a line!
