There should not be any parentheses between "console" and ".printf"

Also, the instructions ask that the message printed should include " can code in Java!"

i tried to use it as a new object but it didn't work to, and i tried to use the exist object and also not working in the task !! String firstName = "Hadi Ahmed"; console.printf("YOUR NAME %s",firstName);

Wow !! now i got it, the output of console object is console data type, so i would work only on consoles

You're still missing the part of the message with " can code in Java!"
