Do you mean "public class HelloWorld { public static void main(String[] args) { ... } }"?

Or the ridiculous Spring abstractions that many people insist on?

The former is a minor nuisance, easily filled in by an IDE. The latter is far worse, unnecessary bloat and complexity. Architecture Astronaut stuff.

These days hello world in Java is just:

```void main() {print("hello world"}``` And you can skip the compile step as well and run it with just `java yourFile.Java`

Since JEP 495 they have made "simple programs" very simple.

yes. main() is the room and print("hello world") the bed.

with the castle I'm referring to the whole myriad of things that must be done to be able to compile this. But, as I said, at least drop in a library, possibly via Gradle.
