bradboimler comments on I just started my first course without having to dismiss "public static void" in the first lesson as "we'll get to that later". I'm loving this.

If you import java.lang.IO.println statically, you can simply write println

import static java.lang.IO.println;

static void main() {
  println("Hello, World!");
}

Ah, interesting. I haven't kept up with the newest Java changes, so you kind of answered that backwards for me. Being able to just use IO.println() is already pretty good and for sure what I'd prefer over having to add an import. Seems to also be a new addition in Java 25, so I guess, Hello World looks a lot different all of a sudden.

Also interesting that this kind of static import doesn't work with System.out.println, I'm guessing because out is already a field of System rather than a package or type. It can be used to write it as out.println, but yeah, not much of a point anymore when IO.println exists.

My code was merely a demonstration that just println is possible now. Like you, I'd prefer IO.println in "real" code. My bar for static imports is extremely high.

Static imports are only for static fields and methods. System.out::println is an instance method.
