Thanks Peter, that does make a lot more sense. But now, back to question. If you read the part I've bracketed, below, it seems to imply that the reference itself is changing. Why "new reference", as if a new reference is being created as a result of passing the object to the method?
Thanks you're a great help.
(#8) When you pass a reference to an array as an argument to a method call, (you pass a new reference to the original array).
