The Collections API is a set of classes and interfaces that support operations on collections of objects.
The Collections API in Java refers to the set of interfaces and classes provided by the Java Collections Framework (JCF) to represent and manipulate collections of objects. The Java Collections Framework is a set of classes and interfaces that provide commonly reusable collection data structures like lists, sets, queues, and maps.
Key components of the Collections API include interfaces such as Collection, List, Set, Queue, and Map, along with their respective implementing classes. These classes provide a standardized way to work with collections of objects, offering various methods for adding, removing, and manipulating elements.
In summary, the Collections API in Java encompasses a set of interfaces and classes that define and implement standard collections, making it easier for developers to work with and manipulate data structures in a consistent manner.
