You are comparing the individual instance of the class with the obj
passed into the method.
There are two objects in play; the Object obj
and the instance of BlogPost
you are operating within.
Your Treet
won't work as that's not what the challenge is dealing with. If you switch out Treet
and use BlogPost
instead, you should be good to go; I'll check in a second.
Steve.

57,712 PointsChecked - yes your code works fine if you use the
BlogPost
class rather thanTreet
.You can do this in fewer lines of code but I don't think it adds much to the readability. Rather than create a new holding vairable,
other
, do the cast inside theequals
parentheses:Like I said, I think this is less clear code-wise but it's worth consideration.
