Actually, the point of passing something in a parameter is so that the class itself doesn't have to define and initialize the array, usually. Usually the main method is where you define it all and...

Not necessarily always. What the compiler didn't like was calling a non-static method in a static way.

Also, you're problem also wasn't initializing. Your methods you cal with the class name have to be...
