what is the difference between collection class vs
collections interface ? not as colection and collections
A collection (sometimes called a container) is an object
that groups multiple elements into a single unit.
Collections are used to store, retrieve and manipulate data,
and to transmit data from one method to another. Collections
typically represent data items that form a natural group,
like an order (a collection of order lines), a mail folder
(a collection of messages), or a telephone directory (a
collection of name/phone-number pairs).
