List Interface In Java

List interface in Java is a part of the java.util package and represents an ordered collection of elements. It’s an interface, which means it provides a blueprint for classes that implement it to define their own specific behavior. Here are some key points about the List interface in Java.


Ordered Collection: Lists maintain the order of elements in which they are inserted. The order of elements can be retrieved by their index (position).

Duplicates Allowed: Lists can contain duplicate elements. Each element can be accessed by its index and might occur multiple times within the list.

Index-Based Access: Elements in a list can be accessed using their index. The index starts from 0 for the first element and goes up to size – 1 for the last element.

Dynamic Size: Unlike arrays in Java, lists can dynamically grow or shrink in size as elements are added or removed.
