Array List in OOPS

An ArrayList in Object-Oriented Programming (OOP) is a dynamic data structure that allows for the storage of elements, similar to an array, but with the ability to grow or shrink in size as needed. Unlike traditional arrays, ArrayLists automatically resize when elements are added or removed, providing flexibility. They maintain the order of insertion and allow random access to elements via indices. ArrayLists are part of the collections framework in languages like Java, offering methods for adding, removing, and querying elements. They are widely used due to their ease of use and ability to handle varying data sizes efficiently.
