toString Issues

[dudeman007]

I am working on some home work and cannot figure out how to call the toString methods from the Point, Square and Cube classes to print out. I know it has to be something stupid, I think I am just toast and my mind is spent. Right now I have ??? in place where the toSting methods should go. Have tried every combination ("class".toString, etc) I can think of. Can anyone tell me where I am messing up? Thanks!!

ok, just quickly, you havent even used your Point class in your main method.
Your toString() method is in your Point class, so you cant call it until you have a Point reference as you have written it.

Duh, should have realized that. Like I said, I'm toast right now. Thanks @sibermewf
