Create a base class and also a class that is derived from the base class. The base class needs to very generic, but would expect at least 4 data items. You must code getters and setters but it is OK to code in-line methods in the same file as this class. The derived class should use the public access specification.
The code can be based on anything you like. Examples could be:
Base Class Derived Class
Music Instrument Trumpet
Cake Birthday or Wedding Cake
Animal Bear, Cat, or more general such as mammal, fish, etc
Assignment:
1. In your main code, create an instance variable based on your base class and also an instance variable based on your derived class.
2. Set variable values for each instance. ( Call the setters).
3. Create a method that will display the values in both objects and call that method. This method should not be part of these classes.
For this step, you pass both instances ( as 2 parameters ) to the method and the method can display the values.4. Create a method named
supportsBoth
that uses the base class as its method argument. Call this method for both the base instance variable and the derived instance variable and have it display an item that exists solely in the base class object.
For this step, you pass only 1 instance but call this method twice. Once passing it the base class object, Once again passing it the derived class object.
Example:
Cake myFirstCake;
// call setters
BirthdayCake myBirthdayCake;
// call BirthdayCake setters ( and inherited setters)
call supportsBoth (myFirstCake)
call supportsBoth (myBirthdayCake)
