I really liked your book and plan to use it when I need to teach people how to code, so thanks a ton.

I tried running `*.java` files without classes (so just `void main`) and I got this error:

```

Hello.java:1: error: class, interface, or enum expected

void main() {

^

```

You need to use --enable-preview for now. When thats stable you won't need to.

I'm not really putting too much effort to call attention to that rn, i'd rather wait
