Study Notes
Introduction to Polymorphism in C#
- Polymorphism in C# refers to the ability of an object to take on multiple forms.
Types of Polymorphism in C#
- There are two main types of polymorphism in C#: compile-time polymorphism and runtime polymorphism.
Runtime Polymorphism in C#
- Runtime polymorphism in C# is achieved through method overriding and virtual methods.
Compile-time Polymorphism in C#
- Compile-time polymorphism in C# is achieved through method overloading.
Meaning of 'Poly' in Polymorphism
- The term 'poly' in polymorphism refers to many or multiple.
Method Overloading in C#
- Method overloading in C# allows a class to have multiple methods with the same name but different parameters.
Purpose of Method Overriding
- The purpose of method overriding in object-oriented programming is to provide specific implementation of a method already provided by its parent class.
Using the 'override' Keyword in C#
- A child class can use the 'override' keyword in C# when a parent class method is marked as virtual.
Benefit of Polymorphism
- The main benefit of polymorphism in object-oriented programming is that it allows for more flexibility and generic code.
Polymorphic Inheritance
- Polymorphic inheritance is respected in object-oriented programming when a child class provides a specific implementation of a method already provided by its parent class.
Abstract Classes
- A root class might be defined as an abstract class when it provides common attributes and methods that can be inherited by child classes.
Abstract Methods
- An abstract method in an abstract class defines a method signature that must be implemented by any non-abstract child class.
Interfaces in C#
- An interface in C# defines a contract that must be implemented by any class that implements it.
Implementing Multiple Interfaces
- A single class in C# can implement multiple interfaces.
Purpose of Interfaces
- An interface in C# provides a way for a class to implement a specific behavior without having to inherit from a parent class.
Feature of Polymorphism
- Polymorphism introduces the feature of method overriding or method overloading into object-oriented programming.
