Java Java Basics Getting Started with Java IO

Using the console's printf method, display a message that says, "First name: ", followed by the first name.

Where am I going wrong ?

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

ok, i'm not sure what's going on, but I just passed the challenge with:

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

try:

String firstName = console.readLine("What is the first name?");
console.printf("First Name:%s", firstName);

You can see https://docs.oracle.com/javase/7/docs/api/java/io/Console.html for an explanation of methods on the Console class. The important thing is the arguments taken and the values returned. If you have further doubts, I can try and explain things in more depth.

But with my code the error is : Did you forget to pass the firstName parameter to the printf function?
