Cube has default and parameterized constructor and volume method(). They share no ancestor other than Object. - Implement a class Size with size() method. This method accepts a single reference argument z. If z reference to a Cube, then size(z) return its volume. If z refers to an object of any other class, then size(z)- returns – 1. Use main() method in Size class to call size(..) method. -
