Question

this is java m. please use netbeans if you can.

7. Person and Customer Classes 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 cus- tomer 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. 8. 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 cus- tomer'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 dis- count 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 construc- tors and the appropriate mutator and accessor methods for the class's fields. Demonstrate the class in a simple program.

//Solution 7

public class Person {
//Fields
private String name;
private String address;
private String phoneNumber;

//Default constructor
public Person()
{
name ="";
address ="";
phoneNumber = "";
}

//Overload Constructor

public Person(String name, String address, String phoneNumber) {
this.name = name;
this.address = address;
this.phoneNumber = phoneNumber;
}
//getters and Setters

public String getName() {
return name;
}

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

public String getAddress() {
return address;
}

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

public String getPhoneNumber() {
return phoneNumber;
}

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

@Override
public String toString() {
return "Name: "+name+", Address: "+address+", Phone: "+phoneNumber;
}
}

//==============================

public class Customer extends Person {
private int customerNumber;
private boolean isMailingList;
//Default Customer
public Customer()
{
//call super class constructor
super();
isMailingList = false;
customerNumber =0;
}
//Overload Constructor

public Customer(String name, String address, String phoneNumber, int customerNumber, boolean isMailingList) {
super(name, address, phoneNumber);
this.customerNumber = customerNumber;
this.isMailingList = isMailingList;
}

//getters and setters

public int getCustomerNumber() {
return customerNumber;
}

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

public boolean isMailingList() {
return isMailingList;
}

public void setMailingList(boolean mailingList) {
isMailingList = mailingList;
}

@Override
public String toString() {
return super.toString()+"\nCustomer Number: "+customerNumber+", Wishing to add mailing list: "+isMailingList;
}
}

//=====================================

public class TestCustomer {
public static void main(String[] args)
{
//Create a customer using overload constructor
Customer customer1 = new Customer("John","2- abc street, City","456-799-9090",101,true);
//Print info using toString()
System.out.println(customer1);
//Create another customer using default Constructor
Customer customer2 = new Customer();
//set Customer attributes
customer2.setCustomerNumber(102);
customer2.setMailingList(false);
customer2.setAddress("New york City");
customer2.setName("Mike");
customer2.setPhoneNumber("890-4567-900");
System.out.println();
//Print info using toString()
System.out.println(customer2);
}
}

//Output

"C:\Program Files\Java\jdk1.8.0_221\bin\java.exe" Name: John, Address: 2- abc street, City, Phone: 456-799-9090 Customer Number: 101, Wishing to add mailing list: true Name: Mike, Address: New york City, Phone: 890-4567-900 Customer Number: 102, Wishing to add mailing list: false Process finished with exit code o

//=========================

import java.text.DecimalFormat;

public class PreferredCustomer extends Customer {
private double amount;
private double discount;

//Default customer
public PreferredCustomer()
{
amount =0;
discount =0;
}

//Overload constructor

public PreferredCustomer(String name, String address, String phoneNumber, int customerNumber, boolean isMailingList, double amount) {
super(name, address, phoneNumber, customerNumber, isMailingList);
this.amount = amount;
discount = calculateDiscount();

}
//getters

public double getAmount() {
return amount;
}

public double getDiscount() {
return discount;
}

/**
*
* @return discount based on customer spends
*/
public double calculateDiscount()
{
if(amount>=500 && amount<1000)
discount = 0.05;
else if(amount >= 1000 && amount <1500)
discount = 0.06;
else if(amount >=1500 && amount < 2000)
discount = 0.07;
else if(discount >= 2000)
discount = 0.10;
else
discount =0;
return discount;
}
//setters

public void setAmount(double amount) {
this.amount = amount;
}

/**
*
* @return String representation of object
*/
@Override
public String toString() {
return super.toString()+"\nAmount spends: $"+String.format("%.2f",amount)+", Discount Earned: "+calculateDiscount()*100+"%" ;
}
}

//===============================

public class TestPreferedCustomer {
public static void main(String[] args)
{
//Create customer
PreferredCustomer preferredCustomer=
new PreferredCustomer("Tim Marker","Pie Street, City Enclave","567-8904=900",1001,true,1400);
//Print info using toString()
System.out.println(preferredCustomer);
}
}

//Output
