Java Java Objects (Retired) Delivering the MVP Defaulting Parameters

``` ------- public void addItem(Product item){ System.out.printf(item.getName()); }

The above code is the one that i added in the shoppingcart.java file in the Java Objects section "Delivering the MVP".

It is compiling fine and giving the output. But i get a message saying "System.out" is not giving the 1 Yoda PEZ dispenser" output.

I uncommented the code in Example.Java as instructed.

Example.java
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);
  }

}
ShoppingCart.java
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(item.getName());
  }
}
Product.java
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;
  }
}

You didn't override the addItem() method the way they wanted you to. You weren't supposed to print anything. They wanted you to call the original addItem() method, so as not to repeat any code.

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){
    addItem(item, 1);
  }
}

It worked. I did not really understand what was expected.

Thanks !!!
