Compiler error

I am not sure what I am doing wrong here.

Name.java 
// I have setup a java.io.Console object for you named console
 {
  public static void main(String[] args) {
    Console console = System.console();
String firstName = "Chris";
  console.printf("Hello my name is %s\n, firstName"); }
}

Hello Christopher,

The instructions never ask you to implement the main method. They just want you to follow each step explicitly as if you were writing within the main method:

Step 1: Define a string variable named firstName that stores your name. Set the value to your name.

     String firstName = "Chris";

Step 2: Call the printf method on the console object and make it write out " (YOUR-NAME) can code in Java!"

     console.printf("Chris can code in Java!");

Step 3: Now replace (YOUR-NAME) in the console.printf expression with the firstName variable using the string formatter.

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

I hope that helps,

Chris
