I need help AGAIN!

Is this how you do this?String firstName = "Austen"; console.printf("firstName can code in Java!", firstName);

Name.java 
// I have setup a java.io.Console object for you named console
String firstName = "Austen";
console.printf("firstName can code in Java!", firstName);

When you use printf to place a variable into a String you need to place a placeholder character in your String in the spot where you want to place said variable. The placeholder for String values is %s so for this task the string has to look like this:

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

The %s will be replaced by the contents of the firstName variable by the printf method when it prints the String.

Sloooooooooooooow down. Watch the videos over again. Try things out in your own text editor/Workspaces. Learning to code is hard but it's completely achievable; takes time, patience, and a strong attention to detail. You won't do yourself any favors by rushing from challenge to challenge and then rushing to the community for help on everything.

Take your time, do challenges a few times so you really cement their concepts in your brain. You got this.
