The Java Collections Framework is a set of classes and interfaces in Java that provide implementations of common data structures like lists, sets, and maps. It offers a unified interface for working with collections of objects.
Imagine the Java Collections Framework as a toolbox filled with different tools for organizing objects. Each tool has its own purpose (e.g., List for ordered collection) but they all work together seamlessly.
LinkedList: A type of list implementation in the Java Collections Framework where each element contains a reference to the next element.
HashSet: A type of set implementation in the Java Collections Framework that does not allow duplicate elements.
HashMap: A type of map implementation in the Java Collections Framework that stores key-value pairs and allows fast retrieval based on keys.
