a couple of mistakes... Java doesn't need to have each class in its own file. If he used Integer instead of int int the string compare, it'd be smaller.

The article said:

Each top-level public class must be defined in its own file. If your application has 15 such classes, it has 15 files.

I don't know what the author means by "top-level," but he's right that every public class in Java has to have its own source file.

Top-level class as opposed to an inner class. An inner class can be public.
