Courses Plus Student 6,497 PointsAccording to wiki: The Java collections framework (JCF) is a set of classes and interfaces that implement commonly reusable collection data structures.[1]
Although referred to as a framework, it works in a manner of a library. The JCF provides both interfaces that define various collections and classes that implement them.
Almost like a collection of data classes that are connected to a structure or interface that allows you to reuse code between the classes.
