Join Barron Stone for an in-depth discussion in this video Override inherited methods, part of Programming Fundamentals in the Real World.
- Nowadays, not all cars run on gasoline, some are electric.…Electric cars have a radio and windows,…so they could inherit those methods from the Car class.…An electric car also has a color and manufacturer.…This is a white Nissan,…so it should inherit those data fields…from the Vehicle class as well.…Now, this is where I run into a bit of a problem.…The drive method for the Vehicle class uses gas,…but my electric car doesn't.…It uses electricity,…so that drive method doesn't make sense.…To create an Electric car subclass…that inherits from the Car and Vehicle classes,…I need to replace that gas-powered drive method…from the Vehicle class…with a specially designed, eco-friendly…electric-powered drive method.…
Here I have start_03_02_class_inheritance…open from the exercise files.…Now, I'll create a new class for electric cars called eCar,…which will inherit from the Car class.…Since eCar inherits the Car class,…it'll have the window and radio methods from it.…And, since the Car class inherits the Vehicle class,…
