This task is a good illustration of how deep the nesting can go. You end up with a method inside a class inside a method inside a class. Is there a limit to how much nesting is possible?

Confusing task . Don't forget to change the return types of the static methods:

public static double getHeight(HasHeight rectangle) {return rectangle.getHeight();}
