You mean this?
Now Java supports top-level instance main methods and class-less compact files. That means now the following declaration is valid:
void main() { System.out.println("Hello from Java 25!"); }I enjoy that the monstrous
System.out.printlnis still right below. 🙃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 becauseoutis already a field ofSystemrather than a package or type. It can be used to write it asout.println, but yeah, not much of a point anymore whenIO.printlnexists.Ah, interesting.

Seems to also be a new addition in Java 25, so I guess, Hello World looks a lot different all of a sudden.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.

Oh come on, please don’t kill the
public static void main(string args)meme!I’ll be honest, I don’t get the point of this feature. It’s nice for beginners or for writing small, quick, programs…but for the overwhelming majority of all java code I don’t see it being useful
the trend of serverless means that people are writing a ton more programs that are smallish single endpoint things. not that a ton of people are using java there, but that was a major motivation for c#
Sure, but I think the argument in favor of this feature is that the overwhelming majority of people picking up programming for the first time tend to be beginners, so if it helps them learn the basics before having to grapple with OOP then it is worthwhile.
