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.

To expand on that you can never instantiate an object of type answer07 since it's a static class.

(For the students here the "static" modifier means "it's on the class, not the object". Non-static will only be accessible as a "obj.whatever" but static is accessible by "Class.whatever")

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).

It looks like exactly 4 characters are missing, so public and static would fit, but I never saw static instead of public static, so I think you're right. On the other hand, I don't use Java anymore and couldn't be bothered about such details
