What is the problem with this code?

public void addItem(Product item) { System.out.printf("%s",item.getName()); } I am geting this message.
Did you uncomment the line in Example.java? The output from System.out does not show the 1 Yoda PEZ dispenser

Make sure you uncomment

cart.addItem(dispenser);

from Example.java

I have uncomment that line

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

The only way this differs is that I am also logging a 1 because this assumes that only 1 is being added when addItem is called.

jason phillips I had the same problem. Do you know why this would be invalid? Or would it have just been bad practice?

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