I've been given an assignment that involves inheritance on BlueJ.
The superclass/ parent class has the following line of code:
abstract void changeSize(int newHeight, int newWidth);
The classes I am dealing with represent different shapes, where the changeSize methods are defined by two parameters for the size, whereas some are only defined by one parameter.
My task is to correct this problem, but I have no idea where to start.
Any help is greatly appreciated
