==Collections==

Collections represent a group of variables of the same data type.  The organization of the collection depends upon the type of collection.  Typical collections natively supported by programming languages include [[Array|arrays]], but also can include [[Tree (data structure)|trees]], lists, [[queue]]s, stacks, etc.  Some languages provide iterators which provide a means of processing through each item in the collection.
