Hi jinhwa,

Craig imported Console class for you and named it "console". So to use the printf method from the Console class you need to call the name of the Class object. And it is "console" and then the function name ... printf(). Inside the parenthesis place your text. 

String firstName = "jinhwa";
console.printf("%s can code in Java!", firstName);
// dont forget to call the console befor printf

The printf method expects a String formatter %s inside " " ! Where you place it, there will be your String variable (firstName). Don´t forget the comma after the second "

I hope it clears thing up :)
