Hi Kimberli,

1) There's no need to declare firstName again. In fact, the Java compiler won't allow the variable to be declared more than once.

2) You'll need to use a placeholder, known as a formatter, to follow the printf method's syntax rules for telling the Java compiler that you have a string variable you want to print out. You'll want to use the %s string formatter, and after a comma, state which string variable you want to print out.

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

You'll be writing something similar to that last line for step 4.

Hope this helps!

Thank you, CJ
