Sales Promotions $(80)$

Overview:

$4$

A retailer runs weekly sales promotions targeting certain customers. If a customer has been targeted for a promotion, a representative from the sales department will call him or her and discuss something of personal interest during the conversion. The retailer runs a football promotion on Sundays, a high$-$tech promotion on Tuesdays, and a bring$-$a$-$friend promotion on Fridays. On Sundays, a rep will call customers who enjoy football attempting to sell them football$-$related products while discussing the customer's favorite team. On Tuesdays, a rep will call customers with a grade point average $($GPA$)$ of $3\mathrm{.}75$ or higher to sell them non$-$fiction books while discussing the customer's favorite subject. On Fridays, a rep will call customers who have one or more friends on record to sell them any product and will ask permission to call their friend as well.

This program includes the following six classes: Customer, Record, SportsRecord, GPARecord, FriendsRecord and SalesPromotionDriver. The first five classes are just used to create simple objects which are manipulated by the sixth class.

Customer class

Customer has the following private instance variables. For each there is a mutator and an accessor method.

private String name

private String phoneNum

private String sport

private String team

private double gpa

private String subject

private int numFriends

String friends

There is a single constructor that accepts a value for each instance variable $($use the order above$).$ You can add a default method if you so desire, but it is not necessary.

Record class

Record is an abstract class.

Record has the following private instance variables. For each there is a mutator and an accessor method.

private String name

private String phoneNum

private int index

There is a single constructor that accepts a value for each instance variable $($use the order above$).$ You can add a default Constructor if you so desire, but it is not necessary. There is a toString method that includes the name and phone number and is incorporated into the toString of the each of it$$s three subclasses.

SportRecord class

SportRecord is a subclass of Record.

It contains one additional private instance variable for which there is a mutator and an accessor method.:

private String team

$5$

There is a single constructor that accepts a value for each instance variable of the super class and for this classes$$ instance variable. $($Remember to use super$).$ You can add a default constructor if you so desire, but it is not necessary.

There is a toString method that includes the name and phone number $($use super.toString$())$ and the team as shown in the output. i$.$e$.$:

name: Sarah Johnson phone number: $2123231245$

favorite team is the Eagles

GPARecord class

GPARecord is a subclass of Record.

It contains one additional private instance variable for which there is a mutator and an accessor method.:

private String subject

There is a single constructor that accepts a value for each instance variable of the super class and for this classes$$ instance variable. $($Remember to use super$).$ You can add a default constructor if you so desire, but it is not necessary.

There is a toString method that includes the name and phone number $($use super.toString$())$ and the subject as shown in the output. i$.$e$.$:

name: Javier Jones phone number: $8568768765$

favorite subject is the Physics

FriendsRecord class

FriendsRecord is a subclass of Record.

It contains one additional private instance variable for which there is a mutator and an accessor method.:

private String friends

There is a single constructor that accepts a value for each instance variable of the super class and for this classes$$ instance variable. $($Remember to use super$).$ You can add a default constructor if you so desire, but it is not necessary.

There is a toString method that includes the name and phone number $($use super.toString$())$ and the friends as shown in the output. i$.$e$.$:

name: Javier Jones phone number: $8568768765$

friends are Maria Regina,$9086547654$

SalesPromotionDriver class

This class includes a static predefined array of type Customer, a private method called matchCustomers, and a main method.

For this problem use the following $($insert inside the class statement$)$

final static Customer$[]$ customers $=\{$

new Customer$("$John Smith" $,"9084321212",$ "football",

"Giants", $3\mathrm{.}61,$ null $,0,$ null$),$
