Hi Zach,

You may need to import Date to your Example class just like you did in the Treet class.

import java.util.Date;

I have the same problem.

I've already found out that I have to import java.util.Date also in my Example.java file, but I'm not sure why you have to do this.

I thought that it works like in some other programming languages (for example C++ if I remember correctly) - if I import Treet.java, where util.Date is already imported I shouldn't have to import it again.

I had the same issue just as mentioned here by Marcin and agree with him that once imported in the Treet class why should I need to re-import again in the Example main class. I could only think of the reason following reason below.

Since the scope of the Date and its usage is inside the Treet Class whereas in the main Example we are passing a new Date object. This new Date object need to be created in Example even before the Treet Object constructor is ready to receive the Date object to initialise it. This means Example must import Date class to create the new Date object before passing it off to the Treet.

If someone else has a some other explanation then please add your comment.

Thank you :)
