IO challenge Task 3 of 4

I've indicated the line console.printf("First name: %s", firstName); but it still shows errors.

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

Hi there,

This is a strange one. Your code is fine. However, the tests are complaining about the order you have your first two lines of code in. If you switch them around, so declare firstName first, your code will pass. 

String firstName = console.readLine("What is your name");
String lastName = console.readLine("What is your last name");

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

I don't know why this is.

Steve.

Technically it should work fine right? Thanks for the feedback!! :)

Yes. It should work, as far as I am aware. I see no reason that the order of those two variables affects their use downstream of that point.

Maybe you should try to replace this line <<console.printf("First name: %s", firstName);">> by this one <<console.printf("First name: %s , Lastname : %s", firstName,lastName);>> I am not very sure but I think that since you declared two variables, maybe the java compiler is expecting two variables.
