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% discount on all future
purchases.
When a preferred customer spends $1,000, he or she gets a 6% discount on all future
purchases.
When a preferred customer spends $1,500, he or she gets a 7% discount on all future
purchases.
When a preferred customer spends $2,000 or more, he or she gets a 10% discount on
all future purchases.
Design a class named PreferredCustomer , which inherits from the Customer class you cre-
ated 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.

Name: Julie James Address: 123 Main Street Telephone: 555-1212 Customer Number 147-A049 Mailing List: YES Purchases: $1,750.00 Discount level: 0.07
