public class CustomerPurchases {
	private static int customerNumber;
	private int quantity;
	private String firstName, surname, product;
	private double price;


	public CustomerPurchases(String fn, String sn, String pr, double p, int q) {
		firstName = fn;
		surname = sn;
		product = pr;
		price = p;
		quantity = q;
		customerNumber++;
	}


	public int getCustomerNumber() {
		return customerNumber;
	}


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


	public int getQuantity() {
		return quantity;
	}


	public void setQuantity(int quantity) {
		this.quantity = quantity;
	}


	public String getFirstName() {
		return firstName;
	}


	public void setFirstName(String firstName) {
		this.firstName = firstName;
	}


	public String getSurname() {
		return surname;
	}


	public void setSurname(String surname) {
		this.surname = surname;
	}


	public String getProduct() {
		return product;
	}


	public void setProduct(String product) {
		this.product = product;
	}


	public double getPrice() {
		return price;
	}


	public void setPrice(double price) {
		this.price = price;
	}


	static class Printing {


		public static void printlnDetails(CustomerPurchases cp) {
			System.out.println("Customer invoice of " + cp.getFirstName() + " " + cp.getSurname() + " is : $ "
					+ cp.getPrice() * cp.getQuantity());
		}


		public static void customerPurchaseReport(CustomerPurchases cp) {
			double price = cp.getPrice();
			System.out.println("REPORT OPTION");
			System.out.format("%s %.2f \n", "PERCENTAGE TAX 15% : $", price * 0.15);
			System.out.format("%s %.2f \n", "COMMISSION 8.5% : $", price * 0.085);
			System.out.format("%s %.2f \n", "DISCOUNT 10% : $", price * 0.1);
			System.out.format("%s %.2f \n", "TOTAL (Price + Tax) – (Discount + Commission) = $",
					(1 + 0.15 - 0.1 - 0.085) * price);
		}


	}


	public static void main(String args[]) {
		CustomerPurchases guitar = new CustomerPurchases("Dan", "Stevens", "Fender Stratocaster guitar", 250, 1),
				drum = new CustomerPurchases("Thomas", "Richardson", "Hoshino Gakki drum", 120, 3),
				micro = new CustomerPurchases("Leila", "Ambers", "Fujimi Boya BY-WHM8 microphone", 53, 2);
		Printing.printlnDetails(guitar);
		Printing.customerPurchaseReport(guitar);
		Printing.printlnDetails(drum);
		Printing.customerPurchaseReport(drum);
		Printing.printlnDetails(micro);
		Printing.customerPurchaseReport(micro);
	}
