Make sure you check Community answers before you, by clicking on "Wrapping Up" right above the title of your question.

The last in the following line:

Java -> Java -> Objects -> Delivering the MVP -> Wrapping up

Here is direct link just in case

https://teamtreehouse.com/community/code-challenge:6072

And here is one of the questions that will shed light on your problem

https://teamtreehouse.com/community/how-do-i-pass-the-author

As you can see the problem of your code is that you don't use arguments , or String[] args in order to pass them to create new User from them.
