An instance variable is a variable declared in a class that has a separate copy (value) for each object created. This tutorial will expand on the Class Introduction tutorial by demonstrating how to create and use instance variables in our Box class. One thing that every Box has in common is dimensions. A Box has length, width, and height. We are going to declare variables that represent each of those values. These variables are defined as instance variables. Then we will create three types of boxes: small, medium, and large - these will represent three distinct objects and each one will have different dimensions. Finally, we will create a method in the Box class that will display the volume of each box object to the console.
