A retail store has a preferred customer plan where customers can earn discounts on all their purchases. The amount of a customer's discount is determined by the amount of the customer's cumulative purchases in the store as follows: a. When a preferred customer spends $500, he or she gets a 5 percent discount on all future purchases. b. When a preferred customer spends $1000, he or she gets a 6 percent discount on all future purchases. c. When a preferred customer spends $1500, he or she gets a 7 percent discount on all future purchases. d. When a preferred customer spends $2000 or more, he or she gets a 10 percent discount on all future purchases. Design a class named Person with fields for holding a person's name, address, and telephone number. Write one or more constructors and the appropriate mutator and accessor methods for the class's fields. Next, design a class named Customer, which extends the Person class. The Customer class should have a field for a customer number and a boolean field indicating whether the customer wishes to be on a mailing list. Write one or more constructors and the appropriate mutator and accessor methods for the class's fields. Next, design a class named PreferredCustomer, which extends the Customer class. The PreferredCustomer class should have fields for the amount of the customer's purchases and the customer's discount level. Write one or more constructors and the appropriate mutator and accessor methods for the class's fields. Demonstrate the class in a simple program.
