Write an inheritance hierarchy for classes Quadrilateral, Parallelogram, Rectangle, and Square. Use Quadrilateral as the superclass of the hierarchy. Create and use a Point class to represent the points in each shape. Make the hierarchy as deep as possible, i. e. more than two levels. Specify the instance variables and methods for each class. The private instance variables of Quadrilateral should be the x-y coordinate pairs for the four endpoints of the Quadrilateral. A program that instantiates objects of your classes and outputs each object's area (except Quadrilateral) has been provided.
