Challenge Task 3 out of 4

I need help with the third exercise on the last stage in Java basics. I don't know what I am doing wrong. If anybody were to respond to this please help me. What am I doing wrong?

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

String lastName = console.readLine("What is your last name?");

The words "First Name:" need to be included in the console.printf string.

console.printf("First Name: %s", firstName);

In a string, that is characters within " ", the symbol %s is used because you don't know what the firstName variable will be, therefore it is a reference for the compiler to look for an argument after the string, in this case: firstName .

What you typed would actually work, but the challenge requires you to include "First Name: " in the output. You will find on the rare occasion that some challenges are confusing because they require very specific outputs.
