Dear, Izhar.

You need to know that printf method is used when we have to specify the format of the output data. In this case, as required by the challenge, we have to specify the output such as: First Name: Izhar

It should be like this:

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

String firstName = console.readLine("Enter your first name: ");

String lastName = console.readLine("Enter your last Name:");

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

//%s means that String value of firstName is going to replace %s.

One more thing, you can also directly the print the value of a variable using println(firstName);
