ArrayList
ArrayList is a resizable array implementation of the List interface in Java, part of the Java Collections Framework. It provides dynamic array functionality, allowing elements to be added, removed, and accessed by index, with automatic resizing as needed. It is widely used for storing and manipulating ordered collections of objects in Java applications.
Developers should use ArrayList when they need a flexible, ordered collection that supports fast random access and frequent modifications, such as in data processing, caching, or UI component lists. It is ideal for scenarios where the size of the collection changes dynamically, as it handles resizing automatically, but it may be less efficient than LinkedList for frequent insertions or deletions at the beginning or middle.
