Hi there,

You only need to declare a variable once - so your second String isn't needed, the compiler knows firstName is a String from the first time you told it.

Second, I'm not sure the compiler is expecting you to assign something to the variable, then read in the user's input. (I'll try it in a sec)

So, you can do all this in one line:

String firstName = console.readLine("Enter your first name: ");

Will edit in a sec when I've tried your way

Yep - you can do it over two lines and assign something to the variable initially:

String firstName = "Steve";
firstName = console.readLine("Enter name: "); // omit second String

The above works fine. I'm not saying you should do it that way but you can. ;-)

String firstName = "Steve". It is not necessary to put a name you can do it like this: String firstName;

True. It was a year ago - I guess I'm forgiven. :wink:

However, I was making the point, as per the question asked, that it is ok to assign something to the variable before storing user input in there. It was a deliberate check to see what would work in an attempt to answer the question fully.

String firstName = console.readLine();

It is only asking you to create a variable that will store the users first name. You do not need to put anything between the parentheses yet. The question hasn't asked that of you yet.
