Hi! I think you first need to import java.io.Console and then create an object of type Console and call printf() method on that object, something like: Console console; console.printf("...your output...");

Console.printf requires you to import is from the java library then create an sintance of the console object and then you can use the console.printf however just get used to using System.out.printf because it's a static call it can be used without creating and instance of the object.
