Overloading and overriding

Polymorphism

Polymorphism means many forms (ability to take more than one form). In Polymorphism poly means "multiple" and morph means "forms" so polymorphism means many forms.

In polymorphism we will declare methods with same name and different parameters in same class or methods with same name and same parameters in different classes. Polymorphism has ability to provide different implementation of methods that are implemented with same name.

In Polymorphism we have 2 different types those are

- Overloading (Called as Early Binding or Compile Time Polymorphism or static binding)

- Overriding (Called as Late Binding or Run Time Polymorphism or dynamic binding)

Overloading

Overloading means we will declare methods with same name but different signatures because of this we will perform different tasks with same method name. This overloading also called as compile time polymorphism or early binding.

Method Overloading or compile time polymorphism means same method names with different signatures (different parameters)

Overloading is when you have multiple methods in the same scope, with the same name but different signatures.

//Overloading public class test {     public void getStuff(int id)     {}     public void getStuff(string name)     {} }

Overriding

Overriding also called as run time polymorphism or late binding or dynamic polymorphism. Method overriding or run time polymorphism means same method names with same signatures.

In this method overriding or run time polymorphism we can override a method in base class by creating similar function in derived class this can be achieved by using inheritance principle and using "virtual &override" keywords.

Overriding is a principle that allows you to change the functionality of a method in a child class.

//Overriding public class test {         public virtual getStuff(int id)         {             //Get stuff default location         } }  public class test2 : test {         public override getStuff(int id)         {             //base.getStuff(id);             //or - Get stuff new location         } }

Hi,
In Polymorphism we have 2 different types.

1) Overloading
2) Overriding

Overloading
Overloading means we will declare methods with same name but different signatures because of this we will perform different tasks with same method name. This overloading also called as compile time polymorphism or early binding.

Method Overloading or compile time polymorphism means same method names with different signatures (different parameters)

Overloading is when you have multiple methods in the same scope, with the same name but different signatures.
```
//Overloading public class test {     public void getStuff(int id)     {}     public void getStuff(string name)     {} }
```
Overriding
Overriding also called as run time polymorphism or late binding or dynamic polymorphism. Method overriding or run time polymorphism means same method names with same signatures.

In this method overriding or run time polymorphism we can override a method in base class by creating similar function in derived class this can be achieved by using inheritance principle and using "virtual &override" keywords.

Overriding is a principle that allows you to change the functionality of a method in a child class.

//Overriding public class test {         public virtual getStuff(int id)         {             //Get stuff default location         } }  public class test2 : test {         public override getStuff(int id)         {             //base.getStuff(id);             //or - Get stuff new location         } }
