Please help me with the code challenge. Don't know what I'm doing wrong.

My code is attached,

In my oppinion I did everything right :P But I get the message: Did you uncomment the line in Example.java? The output from System.out does not show the 1 Yoda PEZ Dispenser.

But when I'm click on console it shows it.

Maybe I missunderstood the question?

Please help me. thx

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) {
      int quantity = 1;
     System.out.printf("Adding %d %s to the cart", quantity, 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;
  }
}

I think it wants you to use your addItem (Product, quantity ) code in your addItem (Product) method.

Public void addItem (Product product ){ addItem (product, 1); }
