New collection A collection in programming is a program object that contains, in one way or another, a set of values of one or different types, and allows access to these values.

The collection allows you to write values to itself and retrieve them. The purpose of a collection is to serve as a repository for objects and provide access to them. Collections are usually used to store groups of objects of the same type that are subject to stereotyped processing. Various methods can be used to refer to a specific element of a collection, depending on its logical organization. An implementation may allow individual operations to be performed on collections as a whole. The presence of operations on collections in many cases can greatly simplify programming.
