I'm not sure why the below code is not passing, I have uncommented the line in Example.java so that the argument of adding just the dispenser is passed, but it seems like there's no output. I'm thinking it might have something to do with the printf statement but I am not sure where the problem could be in it.
Thanks for the help.
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);
Product dispenser = new Product("Yoda PEZ dispenser");
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());
}
public void addItem(Product addedItem) {
System.out.printf("Adding %s to the cart.\n", addedItem.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;
}
}

in the shopping cart class you in your new method that does not take a quantity, you need to call the addItem method thats already been defined. since this method will always add 1 item, you can just pass in 1 as the quantity argument and the addedItem parameter as the item argument
public class ShoppingCart {
public void addItem(Product item, int quantity) {
System.out.printf("Adding %d of %s to the cart.%n", quantity, item.getName());
}
public void addItem(Product addedItem) {
addItem(addedItem, 1);
}
}
while your current way will work, since you already have this method defined its better to go ahead and use it to avoid duplication. also the challenge is expecting you to do it this way

"Adding %s to the cart.\n"
to
"Adding 1 of %s to the cart.\n"
