I am working on Java. It says to replace the <YOUR NAME> variable with a string I have done this but it says I am wrong

what could I be doing wrong?

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

Hello,

Whenever you use %s in a string, you have to tell Java what to replace it with. For example:

console.printf("%s is a programming language.", "Java");

Good luck with Java.

Hi Trevor,

Looks like you're using a %s placeholder, but then not giving it a value. Here's how those work:

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

Good luck!
