Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named (Customer) that is a subclass of the (Person) class. The (Customer) class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.

Inheritance using Interface: Create a new Player Interface. This will have common attributes defined for a player and have at least two methods that will need to be implemented in the derived classes. Here is an example: public interface Player {String getName();int getStats();String getSport();} Create NFL Player and NBA Player concrete classes that will implement Player interface. Develop appropriate unit tests.Create an abstract class called Shape with the protected member String shapeName. It should have two public abstract methods getArea and getVolume. Finally, it should contain a public String method called getName which returns the shapeName. You should create a Circle class, Square class, Rectangle class, Triangle class which extend the Shape class. Each class should contain the necessary private variables. For example, a square has a side. The area and the volume can all be derived from the side value so the only private variable necessary for the square class is the side. The circle requires a radius. The triangle requires a base, length and a height. Finally, the rectangle requires length, height and width. The classes should also contain constructors and appropriate implementations of the two abstract methods getArea and the getVolume. **Shape Calculator** Enter 1 for a Circle Enter 2 for a Square Enter 3 for a Rectangle Enter 4 for a Triangle Enter 5 to Exit You should use a…
