     tuna tunaObject = new tuna();


Someone care to explain why you need to type "tuna" at the beginning and "tuna()" at the end if you already stated that you're going to use the tuna class at the beggining?
I think I understand the "tunaObject" is(the variable to which you will assign the new class in the main class, right?), but the "new" is still kind of ... I don't understand it either...

No, I read the following...

>It is probably best understood that to some degree a class is a coupling of memory allocation directives with compile-time or run-time mapping of names to relative addresses, plus other language specific features.

And my first reaction was "Oh geeze, this person is pulling that one out of their ass".
