sorry, im stumped .. seems simple enough i must be missing something so obvious its ridiculous

keeps telling me the output does not show the dispenser..the code is baby simple..what am i doing wrong??? its too early ZZzz help please.

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");

     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 */
  }


  public void addItem(Product thing)
  {
    System.out.printf("Adding 1 %s to the cart.%n",thing.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;
  }
}

In your new addItem-method (the one that only takes a Product), you are not supposed to write an output yourself. Instead, you should call the pre-existing addItem-method with your Product and a quantity of 1.

ahhhh, the whole "dont repeat your self " i forgot that ...seems silly though since we never ask the user to enter a quantity we are hardwiring it in the code
