Console.printf

What does it mean to pass the firstName parameter to the printf function? I am confused why my line 5 and 6 are not working

IO.java 
String firstName = "Mave";
console.readLine ("%s", firstName);
String lastName = "Haimbodi";
console.readLine ("%s", lastName);
firstName = console.readLine ("First name:");
console.printf ("First name: %s", firstName);

// I have imported java.io.Console for you.  It is a variable called console.

You have a couple lines that are a bit weird. If calling readline, you need to provide prompts containing information about the value you want back. Additionally, the point of calling readLine is that it returns a value. However, I think the message it's giving you is probably a flaw in their challenge verification code. For the record, it accepts:

// I have imported java.io.Console for you.  It is a variable called console.
String firstName = console.readLine ("First name:");
String lastName = console.readLine ("Last name:");
console.printf ("First name: %s", firstName);
console.printf ("Last name: %s", lastName);

You'll note that the line to output the first name is the same as in your code. (so implicitly, if the line it thinks is wrong is correct, then it's tripping over something else)
