Hello all,

I have a quick question regarding the way the size instance method works
for Arrays.

When an array is asked for its size multiple times in a piece of code
(say a method). Which of the following happens?

a) The size is calculated every time the array is asked for it.
b) The size is assigned to an instance variable the first time it is
calculated   and then returned when the array is subsequently asked for
its size.

Any reply to this question would be gladly received.

Thanks in advance.

Matt.
