Hi Fernando

So you're stuck on task 3 so you're code so far must look something like below?

String firstName = console.readLine("Please enter your first name: ");
String lastName = console.readLine("Please enter your last name: ");

In that case what it asks is to use the printf method to format the message "First name: " and pass the firstName variable into it. This takes the format of the code below.

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

The %s acts as a place holder for string data types and then tell it which variable to put in its place. Task 4 asks for the same thing but using last name so that should give you the chance to tweak the code a little.

Hope it helps!

Stephen
