Here are 2 interrelated classes, namely Product and Store, to calculate the discount and total cost of the pizza ordered:

a. There is a minimum of 4 smell code in the code below, please mention and explain your answer! b. D0 a refactor to fix the code smell!

Product.java

public class Product {

private String name = "";

private double price = 0.0;

private double shippingCost = 0.0;

private int quantity = 0;

public String getName(){ return name; }

public double getPrice(){ return price; }

public double getShippingCost(){ return shippingCost; }

public int getQuantity(){ return quantity; }

Product(String name, double price, double shippingCost, int quantity){

this.name = name;

this.price = price;

this.shippingCost = shippingCost;

this.quantity = quantity;

}

public double getTotalCost(){

double quantityDiscount = 0.0;

if((quantity > 50) || ((quantity * price) > 500)) {

quantityDiscount = .10;

} else if((quantity > 25) || ((quantity * price) > 100)) {

quantityDiscount = .07;

} else if((quantity >= 10) || ((quantity * price) > 50)) {

quantityDiscount = .05;

}

double discount = ((quantity - 1) * quantityDiscount) * price;

return (quantity * price) + (quantity * shippingCost) - discount;

}

}

Store.java

import java.util.ArrayList;

public class Store {

public ArrayList theProducts = new ArrayList();

public void addAProduct(Product newProduct){

theProducts.add(newProduct);

}

public void getCostOfProducts(){

for(Product product : theProducts){

System.out.println("Total cost for " + product.getQuantity() + " " + product.getName() + "s is $" + product.getTotalCost());

System.out.println("Cost per product " + product.getTotalCost() / product.getQuantity());

System.out.println("Savings per product " + ((product.getPrice() + product.getShippingCost()) - (product.getTotalCost() / product.getQuantity())) + " ");

}

}

public static void main(String[] args){

Store cornerStore = new Store();

cornerStore.addAProduct(new Product("Pizza", 10.00, 1.00, 52));

cornerStore.addAProduct(new Product("Pizza", 10.00, 1.00, 26));

cornerStore.addAProduct(new Product("Pizza", 10.00, 1.00, 10));

cornerStore.getCostOfProducts();

}

}
