Introduction to Collections Framework Collections Framework: The Collections Framework provides a well-designed set of interfaces and classes for storing and manipulating the groups of data into a single unit. The collections framework is a unified architecture which is used to represent and manipulate collections. The framework allows the collections to get manipulated independently, additionally it reduces the programming efforts and increases performance. It includes implementation of interfaces and algorithms. Basically it is a unified architecture that consists the following collections: Interfaces: These are the abstract data types that represent collections. With the help of interfaces we manipulate collections independently. A hierarchy is generally formed ...
