Define String variable firstName that stores your name. Unable to compile

public class Name { public static void main(String[] Args) { Console console = System.console(); String firstName = "Oliver"; console.printf("Hello" + firstName); } }

Name.java 
public class Name {
  public static void main(String[] Args) {
    Console console = System.console();
    String firstName = "Oliver";
    console.printf("Hello" + firstName);
  }
}// I have setup a java.io.Console object for you named console

Hey Oliver, we don't need to set up a console object, the comment already let us know that this was set up.

Second, when you are using print f you don't need to use the to concatenate the string with the addition sign.

All that is needed is to declare your variable then pass in the value like below

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

HI Oliver,

You've done that correctly, but added all the other stuff that the compiler isn't looking for. It literally just wants the one line:

String firstName = "Oliver";

:wink: :+1:
