Method Overriding:

 Method overriding isthe mechanism same method name with same arguments and return types associatedin a class and its subclass. Overriding is mainly used in functions.

Only those methods are override that methods are declaredwith keyword virtual in the base class.

Example:

Class A

{

    Virtual void add(int a, int b)

    { 

        Return(a+b);

    }

}

Class B:A

{

    Public override void mul(int a, int b)

    {

        Return(a*b);

    }

}

Static void main()

{

    A obj=new A()

    Obj.add(5,6);

    B obj1=new B();

    Obj.mul(5,9):

}
