String firstName = "Tiffany";

The token "%s" goes where you want the name to appear in the output string:

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

Also, for tasks 1 and 2, you don't need the literal strings. You can just assign the "readLine" result directly:

String firstName = console.readLine();
String lastName = console.readLine();
