Java, a versatile and widely-used programming language, offers a robust set of data structures to handle collections of objects efficiently. One of the fundamental data structures in Java is the List interface that provides an ordered collection of elements with dynamic sizing. It is a part of Java Collections Framework, provides a versatile and ordered way to handle collections of elements.

You can use the Java List interface to store objectselements in an ordered collection. It extends the Collection interface. The List interface provides us with various methods for inserting, accessing, and deleting elements in a collection.. In this article, you'll learn how to extend and implement the List interface in Java, and how to interact with elements in a collection.
