Hello mate,

  1. For this exercise, an instance of the Console class has been created for you and is referenced by the variable console; no need to declare it yourself.
  2. The Console class has the method printf(String fmt, Object... args), used for writing a formatted string to the console's output stream. Looking at the documentation, you will see that the Console class has no print() method.
  3. printf(String fmt, Object... args) is non-static and needs to be called on the object instance, console, and not Console.
  4. No need for the opening and closing braces.
Name.java 
// I have setup a java.io.Console object for you named console
{    // (4)
Console console = System.console ();    // (1)
string firstname = "Harry";
Console.print ("%s lernt von anfang an\n", firstname);    // (2)(3)
Console.print ("%s lernt wie soll JAVA screiben\n", firstname);    // (2)(3)
}    // (4)

Hope this helps
