1,121 PointsI'm completely at a loss.
Absolutely no Idea what I am to do here. It is asking me to fulfill an imaginary developer's request, but It won't tell me plainly what to do.
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 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;
}
}

Treehouse Project ReviewerAt the bottom of the Example class, there is a line of code that should be uncommented. The "cart.addItem(dispenser)". What it's asking you to do is create a method "addItem" in the ShoppingCart class that will put just one item in the cart by default, instead of having to specify how many you're putting in (unlike the cart.addItem(pez, 5) above that).
Remember, you can have different instances of a method that do different things depending on the parameters put in.
If you need more help, let me know! I'll be glad to push you in the right direction.
