Error on Bottles of Milk - Java

I tried to enter this example into the workspace myself and I get the following error. 

Exception in thread "main" java.util.MissingFormatArgumentException: Format specifier '%d'

        at BottlesOfMilk.main(BottlesOfMilk.java:8)

My code is:

import java.io.Console;

public class BottlesOfMilk {
    public static void main(String[] args) {
        Console console = System.console();

        for (int i = 99; i > 0; i--) {
            console.printf("%d bottles of milk on the wall...%n");
        }
    }
}

Hi Jim, at the end of the printf statement you forgot to specify what %d was representing, which is the variable "i". Hope that helped!
