Is the class declared static? I assume the “…ic class Answer07” at the top stands for “public class Answer07”.

I don’t think java supports top level static classes (it does have nested static classes, though).

To be needlessly pedantic on this joke, answer07 in itself is not an object, but a class, a blueprint for objects. An instance of that class would be an object. Calling the static function main does also not create an instance of the class in the class loader.

Very useful. I’ll definitely going to use the ranking stuff.
