what does this mean? Print out to the screen using the printf method on console, "First name: " and the user's first name.

There isn't an response data in the task, the system will not let me add a name, and when I try to do the console.printf without it, I get a bummer! message with no explanation

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

Hey Lawrence,

This challenge wants you to output the user's first name gathered from the readLine command. So, let's say we put in "Jimbo" for a first name, the output should read "First name: Jimbo". Notice exactly how the string is formatted, which is the way the challenge wants you to do it.

With that in mind, you have to remember that the %s is a placeholder for the variable in the next argument. "First name" is not a variable, but "firstName" is. So, we have to add in the text we want to the first string and change the variable name to the one we initialized which is "firstName":

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

Given this info, it should be super simple for you to do the last name, as well! :)
