Hi Hezi

You're almost there, you are trying to populate the String.format() method with the variable type not the variable name try the code below and see how you go:

String firstName = "hezi"; 
Console.printf("hello my name is %s",firstName);

Hope this helps

Hi Hezi,

i formatted your code:

String firstName = "hezi"; 
Console.printf("hello my name is %s",String);

You should replace String with firstName. String is a type, but for printf method you need the name of the String.

And to your second question:

IDE´s like Eclipse can´t deal with console, because they have no console environment. Console class are made for Console applications, not for Eclipse or IntellyJ.
