String firstName = ("Brendan"); console printf = ("%s can code in Java!");

change it so the string firstName is included, like this

String firstName = ("Brendan"); console printf = ("%s can code in Java!", firstName);

I am so sorry, I forgot to mention that there is an error in your script, it is console.printf and not console printf

and there is not an equal sign in between console.printf and the statement

Console is capitalized and is a library that you have to import at the top of your file and instantiate it if you want to use it. As in:

import java.io.Console;

public class MyApp{
Console console = System.console();
}

Also, you're accessing the "printf" method of Console, so you don't use the "=" sign, you just pass it your string as an argument. As in:

console.printf("Here's my text string.");

Third, if you want to format a string with a variable, you'll pass them both in as arguments like so:

console.printf("%s is my name", myStringVariable);

If you want to avoid all that stuff, I suggest just using the System.printf() method, rather than Console:

System.printf("%s is my name", myStringVariable);

You also don't need to put parentheses around your variable declarations. This will do:

String myStringVariable = "my string";
