1,681 PointsSmall problem with output.
I tried to have the code output that I am Adding 1 Yoda PEZ dispenser to the cart. When I check preview it says that my output is exactly that but I keep getting the error message.
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);
Product dispenser = new Product("Yoda PEZ dispenser");
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 void addItem(Product item) {
System.out.printf("Adding 1 %s to the cart.%n", item.getName());
}
}
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;
}
}

10,365 PointsHi David,
you have to override the first addItem method that takes a single argument "item". Inside that "second" method call the "first" addItem method and pass it the item and the quantity 1.
public void addItem(Product item) {
addItem(item, 1);
}
Makes sense?

1,681 PointsThanks for your help. I am still having some trouble. I don't fully understand the basic concept of how we can take a method that requires one input and make it so it excepts two. I still got the following error when I entered your code.
required: Product found: Product,int reason: actual and formal argument lists differ in length
Also I don't know how to call the 1 from addItem(item, 1); into the %d from System.out.printf.
Thank you very much for your help thus far and any more help is greatly appreciated.
