Java Arrays and ArrayLists

# Introduction

In this lab, we'll dive into two fundamental data structures in Java: Arrays and ArrayLists. These structures allow us to store and manipulate collections of data, which is crucial for many programming tasks. We'll start with the basic array, then move on to the more flexible ArrayList. By the end of this lab, you'll be able to create, manipulate, and work with both arrays and ArrayLists in Java.

We'll cover:

1. Creating and using arrays
2. Accessing and modifying array elements
3. Introduction to ArrayLists
4. Adding, removing, and accessing elements in ArrayLists
5. Converting between arrays and ArrayLists

Let's get started with organizing our data!
