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.
