List Interface : Part 1- ArrayList || Java Collection Framework ||
Welcome back to our Java Collections series! In the previous video, we gave an overview of the Collection interface, and in this video, we'll be diving deeper into the List interface and its implementation using ArrayList.
List is an ordered collection of elements that allows duplicates and is index-based. There are various types of lists in Java, such as ArrayList, LinkedList, Vector, and Stack. In this video, we'll focus on ArrayList.
ArrayList is a resizable array implementation of the List interface that can dynamically increase or decrease its size based on the number of elements it contains. We'll learn how to create an ArrayList and how to perform various operations on it.
We'll start by demonstrating how to create a 1D ArrayList and add elements to it. Then, we'll cover the various methods to operate on the ArrayList, such as add(), remove(), get(), set(), and others. We'll also demonstrate how to create a 2D ArrayList and add elements to it.
By the end of this video, you'll have a good understanding of ArrayList and its operations. In the next video, we'll continue with the List interface and learn how to implement it using LinkedList.
So, sit tight and let's get started with ArrayList!
