Polymorphism is ability for redefining methods for derived
classesin OOPs.
its of two types:
1.Compiletime : Method overloading
Methods with same name but diff signatures.
Example:
Public class Calculation
public overloads sub Add(x as integer,y as integer)
return x+y
End Sub

Public overloads sub Add(x along,y as long, z as long)
return x+y+z
End sub
End class

2.Runtime :Method Overriding

Two or more methods with same name,same signatures but with
different implementations.

Example:
Public class DrwingObject
Public Overridable function Draw() as String
return "i am in generic object"
End functin
End class

Public class Line inherits DrawingObject
Public overrides functin Draw() as string
return " i am line"
End Function
End class
