Object Oriented Programming: Polymorphism - Java Programming

Let's talk about one of the main "pillars" of object oriented programming, polymorphism, and how it applies in Java. In this video I'll introduce the concept of polymorphism and what it means in a couple straightforward code examples. Hope you enjoy it!

encapsulation and polymorphism are features of good code, whether it's strictly object oriented or just plain C. In plain ol' C we just use opaque pointers to encapsulate. If that opaque pointer can abstract different stuff, it's polymorphic, like the FILE pointer could be an actual file on disk or say a serial port.

Great tutorial on polymorphism, Will! I like how you explain how inheritance and polymorphism in Java are interrelated and how to understand poly and morph in a clear and concise way. You are an excellent teacher!

Better metaphor for polymorphism: you can drive a Jeep, a Ford Truck, a Honda CRV, or even a Lexus Sedan. You have many different types of Vehicles, the kind do slightly different things, but they all work pretty much the same. That's your goal when making polymorphic code.
