For Java 25 which is planned to be released in a couple of weeks:

----- https://openjdk.org/jeps/512 -----

First, we allow main methods to omit the infamous boilerplate of public static void main(String[] args), which simplifies the Hello, World! program to:

  class HelloWorld {
    void main() {
      System.out.println("Hello, World!");
    }
  }
Second, we introduce a compact form of source file that lets developers get straight to the code, without a superfluous class declaration:

  void main() {
    System.out.println("Hello, World!"); 
  }
Third, we add a new class in the java.lang package that provides basic line-oriented I/O methods for beginners, thereby replacing the mysterious System.out.println with a simpler form:

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

    so getting closer to Go's syntax, n'en déplaise à certains, apparently. :-)

      Except for the extra 3 lines of if err for every statement..

        Perhaps that it is coming sooner than you think... It all started with adding Value types, now syntactic refinements à la Go... Who knows? :-) You'll be very happy.

        edit: hold on wait, java doesn't have Value types yet... /jk

Always find 'java is verbose' to be a novice argument from go coders when there is so much boilerplate on the go side of things that's nicely handled on the java side.

Every function call is 3-5 lines in Go. For any problem which needs to handle errors, the Go code is generally >2x the Java LOC. Go is a language that especially suffers from the "code padding" problem.

It's rich to complain about verbosity coming from Go.

Nonetheless, Java has eased the psvm requirements, you don't even have to explicitly declare a class and a void main method is enough. [1] Not that it would matter for any non-script code.
