Dynamic storage of data: ArrayList is a dynamic array that can expand or shrink storage space as needed, capable of storing data of any type.
Traversing and accessing elements: ArrayList offers a variety of methods for accessing, traversing, and manipulating elements, such as get(), set(), remove(), and more.
Adding and deleting elements: ArrayList offers methods like add() and remove() for easily adding and removing elements within the list.
Sorting and searching: ArrayList offers methods for sorting and searching elements, such as Collections.sort() and Collections.binarySearch(), which make it easy to sort and search elements in the list.
ArrayList can be used as both a parameter and a return value in methods, making it convenient for passing data between different methods.
As a fundamental data structure, ArrayList is one of the commonly used data structures in Java, serving as the foundation for implementing other data structures such as stacks, queues, and graphs.
