Try adding firstname as an argument to printf().

You've got your format specifier but it doesn't have anything to display yet.

You can get it to work by passing in a variable as an argument to printf() like this.

String firstName = "Laura";
console.printf("%s can code in Java!", firstName);

Make the string matches exactly what is directed in the questioning. :-)
