String firstName= "tamara";

Hi, you have to turn around your code like this, it should work.

// I have setup a java.io.Console object for you named console
String firstName= "tamara";
console.printf("%s can code in Java!" , firstName);

Like Daniel said it works if you change the order.

The important thing is, that %s is part of the String you want to print. %s is just a placeholder for the additional parameter you provide. You can also use %s multiple times, but you have to provide enough arguments.

String firstName = "Felix";
String lastName = "Sonnenholzer";

console.printf("My first name is %s and my last name is %s", firstName, lastName);

The first %s gets replaced by the first parameter and the second %s by the second and so on.
