So here's the OBJ..
The objective of this assignment is to build a simple program using Inheritance. The application will include seven classes including the one containing the main method. The Product class will be the super class of classes Electronics and Book. The Electronics class will be the parent class of the MP3Player class and the TV class.
The Product class is complete. Your task is to complete the rest of the classes. The requirements for each of the methods in each class are specified in the method signatures.
Method computeSalePrice is common to all classes. However, this method will be overridden in each class because not all objects will have the same Sale Price.
The figure in next page shows a diagram of all the classes involved in this application.
Class ProductApplication is complete. You should get the following output when you run your program.
