collection

In computer science, a collection refers to a data structure that groups multiple elements together, allowing for efficient storage, retrieval, and manipulation of data. Collections can be categorized into various types, such as lists, sets, and maps, each serving different purposes and offering unique functionalities. For instance, lists maintain the order of elements, sets ensure uniqueness, and maps associate keys with values. The collections framework in programming languages like Java provides a robust set of interfaces and classes to facilitate the use of collections, enhancing code organization and performance. Understanding collections is essential for effective data management in software development.
