Question

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. Demonstrate an object of the Customer class in a simple program.

(Instructor request) For the demo, write a main that creates 3 Customers and prints out their information. Make up some names, addresses, phone numbers, etc. so no user input is required.

Explanation / Answer

// Person.java

public class Person {

    private String name;
    private String address;
    private String phoneNumber;

    public Person(String name, String address, String phoneNumber) {
        this.name = name;
        this.address = address;
        this.phoneNumber = phoneNumber;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPhoneNumber() {
        return phoneNumber;
    }

    public void setPhoneNumber(String phoneNumber) {
        this.phoneNumber = phoneNumber;
    }
}

// Customer.java
public class Customer extends Person {

    private int customerNumber;
    private boolean onList;

    public Customer(String name, String address, String phoneNum, int number, boolean onList) {
        super(name, address, phoneNum);
        this.customerNumber = number;
        this.onList = onList;
    }

    public int getCustomerNumber() {
        return customerNumber;
    }

    public void setCustomerNumber(int customerNumber) {
        this.customerNumber = customerNumber;
    }

    public boolean isOnList() {
        return onList;
    }

    public void setOnList(boolean onList) {
        this.onList = onList;
    }
}

// Driver.java

public class Driver {

    public static void main(String[] args) {

        Customer customer1 = new Customer("Judy Smith", "123 Maple Lane", "555-305-9876", 1, true);
        Customer customer2 = new Customer("Bob White", "456 Oak Road", "555-895-4931", 2, true);
        Customer customer3 = new Customer("Garry Goodman", "789 Acorn Avenue", "555-587-2983", 3, false);

        System.out.println("Customer 1:");
        System.out.println(" Name: " + customer1.getName());
        System.out.println(" Address: " + customer1.getAddress());
        System.out.println(" Phone Number: " + customer1.getPhoneNumber());
        System.out.println(" Customer Number: " + customer1.getCustomerNumber());
        System.out.println(" On Mailing List: " + customer1.isOnList());

        System.out.println("Customer 2:");
        System.out.println(" Name: " + customer2.getName());
        System.out.println(" Address: " + customer2.getAddress());
        System.out.println(" Phone Number: " + customer2.getPhoneNumber());
        System.out.println(" Customer Number: " + customer2.getCustomerNumber());
        System.out.println(" On Mailing List: " + customer2.isOnList());

        System.out.println("Customer 3:");
        System.out.println(" Name: " + customer3.getName());
        System.out.println(" Address: " + customer3.getAddress());
        System.out.println(" Phone Number: " + customer3.getPhoneNumber());
        System.out.println(" Customer Number: " + customer3.getCustomerNumber());
        System.out.println(" On Mailing List: " + customer3.isOnList());
    }

}
