The ArrayList constructor is a special method that creates an instance of the ArrayList class. It allows you to initialize an ArrayList object with specific elements or specify its initial capacity.
Think of the ArrayList constructor as a recipe for making a cake. You can choose to start with a pre-made cake mix (initialize with specific elements) or decide how big the cake should be by specifying the size of the baking pan (initial capacity).
add(): This method adds an element to the end of the ArrayList.
get(): This method retrieves an element from a specific index in the ArrayList.
size(): This method returns the number of elements currently stored in the ArrayList.
