Class:A blueprint or template that defines the properties and behaviors of objects. For example, a car class would define the attributes like color, model, and methods like start() or stop().
Instance: An individual occurrence or realization of a class. In our analogy, each car on the road is an instance of the car class.
Variable:A named storage location in memory that holds a value. In this case, objectOne is a variable holding an instance of a class (car).
