Hello World From Java 24

It’s been a while since I did some Java work - middleware that interfaced with Oracle FlexCube and Finacle, which implemented ISO 8583.

Oracle has recently released Java 24 SDK, and I wondered what was new.

The most striking is this:

public void main() {
    println("hello world!");
}

This is a complete application.

And it runs:

What is striking about this?

This is what a traditional Java application looks like:

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("hello world!");
    }
}

This is great because it makes the language more approachable to newbies who do not need to know what a class is or what static is. Or String[]. Or args. Or System.out.

TLDR

Java has begun to take strides to be friendly to newbies.

Happy hacking!
