Question

Design a class named PersonData with the following member variables: lastName firstName address city state zip phone Write the appropriate accessor and mutator functions for these member variables. Next, design a class named CustomerData, which is derived from the PersonData class. The CustomerData class should have the following member variables: customerNumber mailingList The customerNumber variable will be used to hold a unique integer for each customer. The mailingList variable should be a bool. It will be set to true if the customer wishes to be on a mailing list, or false if the customer does not wish to be on a mailing list. Write appropriate accessor and mutator functions for these member variables. Demonstrate an object of the CustomerData class in a simple program.

// CustomerData

public class CustomerData extends PersonData{
   int customerNumber;
   boolean mailingList;
   public CustomerData(String lastName, String firstName, String address,
           String city, String state, String zip, String phone,
           int customerNumber, boolean mailingList) {

       this.customerNumber = customerNumber;
       this.mailingList = mailingList;
   }
   public int getCustomerNumber() {
       return customerNumber;
   }
   public void setCustomerNumber(int customerNumber) {
       this.customerNumber = customerNumber;
   }
   public boolean isMailingList() {
       return mailingList;
   }
   public void setMailingList(boolean mailingList) {
       this.mailingList = mailingList;
   }

  
}

// CustomerDataTest

public class CustomerDataTest {
   public static void main(String[] args)
   {
       String lastName = "Brynes";
       String firstName = "Billly";
       String address = "My local address";
       String city = "Fairborn";
       String state = "Ohio";
       String zip = "45324";
       String phone = "8978789878";
       int customerNumber = 1;
       boolean mailingList = false;
       CustomerData customerData = new CustomerData(lastName, firstName, address,
               city, state, zip, phone,
               customerNumber, mailingList);
      
       System.out.println("Hello " + customerData.getFirstName() + " " + customerData.getLastName());
       System.out.println("You are from " + customerData.getCity() + " " + customerData.getAddress() + " " + customerData.getZip());
       if (customerData.isMailingList())
           System.out.println("You have subscribed to weekly newsletter");
       else
