Creating abstract classes
For people who love cars, hearing the horn is all they need to identify a particular type of car. Many car manufacturers know this and make their cars sound unique as a branding strategy. You will update the Car class to contain a method for the horn functionality of cars.
NOTE: An abstract class cannot have instance objects created from it as it exists to be merely a blueprint from which to be inherited.
