So let's look at the word polymorphism and understand the concept in coding, especially in C sharp
because we have seen one part of polymorphism before.
But now really let's dive deeper.
So what is polymorphism?
Polymorphism is a word that comes from Greek meaning many shapes.
In programming, it refers to the ability of a single interface or method to operate in different ways,
depending on the object it is acting upon.
Think of polymorphism like this.
Imagine you have a universal remote control.
This remote can control different devices like ATV, a DVD player, and a stereo system.
Even though you press the play button on the remote, it can make the TV play a movie.
The DVD player started this, or the stereo player play music.
The same button, the same method works differently based on the device, the object it is controlling.
The key points are one interface many implementations.
So a single function or method can work with objects of different types.
The specific implementation depends on the object that is being referenced at the time.
So if you have different types of animals, each animal makes a different sound.
With polymorphism, you can call them make sound method on any animal and the correct sound for that
specific animal will be produced.
So why would you even bother using polymorphism?
Well, part one is flexibility.
Polymorphism allows you to write more flexible and reusable code.
You can write methods that work with objects of different types without knowing exactly what those types
will be.
And then there is code maintenance.
It makes your code easier to maintain and extend.
You can add new types of objects and simply ensure they conform to the expected interface or base class
without changing the code that uses them.
And this is something that is really important, because sometimes you don't have control over the parent
class or over the interface.
So then it simplifies the code.
Polymorphism helps you to simplify your code as you can treat different types of objects in a uniform
way.
So let's conclude polymorphism is a powerful concept that allows methods to operate on objects of different
types.
It enables flexibility, reusability, and maintainability in your code by allowing one interface to
be used for a general class of actions, where the specific action is determined by the exact nature
of the situation or object involved.
So that's it for this video.
