And most IDEs will autogenerate it for you.

That said, I think it highlights everything I hate about Java:

public class MyClass {

Why does it need to be a class? I'm not constructing anything?

public static void main(String[] args) {

Why is this a method? It should be a top-level function. Also, in most cases, I don't care about the arguments, so those should be left out.

System.out.println("Hello world!");

Excuse me, what? Where did System come from, and why does it have an "out" static member? Also, how would I format it if I felt so inclined? So many questions.

And here are examples from languages I prefer:

C:

#include "stdio.h"

Ok, makes sense, I start with nothing.

int main() {

Makes sense that we'd have an entrypoint.

printf("Hello world");

Again, pretty simple.

Python:

print("Hello world")

Ok, Python cheats.

Rust:

fn main() {

Ooh, entrypoint.

println!("Hello world");

I have to understand macros enough to realize this is special, but that's it.

In C, Python, and Rust, complexity starts later, whereas Java shoves it down your throat.
