Hello, Abstract methods have NO implementation and HAS to be override in sub classes. Class Vehicle{ Public abstract void drive(); } Class Car:Vehicle{ Public override void drive(){ Console.WriteLine("driving a Car"); } } Virtual methods are already implemented and if you want to change the behavior in a subclass you CAN override it. But you dont have to. Class Vehicle{ Public virtual void drive() { Console.WriteLine("driving a vehicle"); } } Class Car:Vehicle{ Public override void drive(){ // this you can do but you dont have to Console.WriteLine("driving a Car"); } } Hope i can help u a little.
