Hi Pixel HD,

So please read again the Example.java file after reading my answer :)

They want from you to create another method (wisely, because the topic is about refactoring, be careful DRY pattern ;) ) that allows others to be able to add an item using just addItem(itemHere) which means add 1 itemHere on the cart

Hope it helps! If not, just let me know, I'll answer the challenge and explain to you why you should do it that way :)

They're asking you to add a second method to the ShoppingCart class. The method's name, which you should see in the commented out code in main() has the same name as the first, but with a different list of arguments.
