I can't even figure out the first lesson.

This happened to me when I was trying to follow along on video as well, and i couldn't figure it out then.

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

Hey Brian!

You got the first line correct and were close on the second one!

When we use a placeholder like %s, we need to tell it what to replace that placeholder with as an argument within the method it's used. So, it will look something like this:

console.printf("%s is a placeholder", thisIsWhatItWillBeReplacedWith);

Note that thisIsWhatItWillBeReplacedWith would be a String variable.

Try and reword what I've just written to suit this code challenge!

Hopefully this should explain the challenge for you but if you get stuck along the way or if there's something you don't understand here, let me know and I'll make sure to help out :)
