Java Java Basics Getting Started with Java IO

Java basics, where's my mistake?

I can't get by this one. It says that I forgot to pass the 'firstName' parameter to the printf while it's right there.

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

something like

String firstName = console.readLine("firstName  ");
String lastName = console.readLine("lastName  ");
console.printf("First name:%s", firstName);
console.printf("Last name:%s", lastName);

The first and lastnames are returned from the readLine method and assigned to variables. These variables are then used in the printf method.
