The array classes have two important variables:
int size
-
Indicates the number of elements in the array. Although the array
may have allocated additional space, this is the number of elements in
use.
item err
-
Indicates the value to return when the array is accessed out of
range.(ex. If the array had a size of 5 and was asked for element 6
or element -1 then the err value would be returned).
