JAVA

PreferredCustomer Class
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:

• When a preferred customer spends $500, he or she gets a 5 percent discount on all
future purchases.
• When a preferred customer spends $1,000, he or she gets a 6 percent discount on all
future purchases.
• When a preferred customer spends $1,500, he or she gets a 7 percent discount on all
future purchases.
• When a preferred customer spends $2,000 or more, he or she gets a 10 percent discount
on all future purchases.

Design a class named PreferredCustomer, which extends the Customer class you created in
Programming Challenge 7. 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.
