I need help being DRY!

read code

ShoppingCart.java 
//So I need to make this work, without repeating my code, (Adding some code into *here*)
  public void addItem(Product item) {
    System.out.printf("Adding 1 of %s to the cart.%n", item.getName());
  }
  public void addItem(Product item, int quantity) {
    System.out.printf("Adding %d of %s to the cart.%n", quantity, item.getName());
    //*here*
  }

Hello Abe Daniels ,

You should simply call one method within the other. In this case, call the one with 2 parameters inside the one with 1. It should look like this:

public void addItem(Product item) {
    addItem(item, 1);
}
