Courses Plus Student 32,914 PointsI don't know what do to here.
I don't know the parameter nor do I understand the instructions. Can anybody help a guy out?
public class Example {
public static void main(String[] args) {
ShoppingCart cart = new ShoppingCart();
Product pez = new Product("Cherry PEZ refill (12 pieces)");
cart.addItem(pez, 5);
/* Since a quantity of 1 is such a common argument when adding a product to the cart,
* your fellow developers have asked you to make the following code work, as well as keeping
* the ability to add a product and a quantity.
*/
Product dispenser = new Product("Yoda PEZ dispenser");
/* Uncomment the line following this comment,
after adding a new method using method signatures,
to solve their request in ShoppingCart.java
*/
cart.addItem(dispenser);
}
}
public class ShoppingCart {
public void addItem(Product item, int quantity) {
System.out.printf("Adding %d of %s to the cart.%n", quantity, item.getName());
/* Other code omitted for clarity. Please imagine
lots and lots of code here. Don't repeat it.
*/
}
public void addItem(Product item)
{
System.out.printf("Adding 1 %s to the cart.%n", item.getName());
}
}
public class Product {
/* Other code omitted for clarity, but you could imagine
it would store price, options like size and color
*/
private String mName;
public Product(String name) {
mName = name;
}
public String getName() {
return mName;
}
}

public void addItem(Product item)
{
// System.out.printf("Adding 1 %s to the cart.%n", item.getName()); <- This is repeating what is already in the
// other addItem method.
addItem(item, 1) // Instead add the item with a default qty. of 1
}
