Question

Folks

I am surprised to see my code working, that I dont have any abstract method in abstract class. But as per rules we should have atleast one abstract method right ? :S

Answer 1

No, you don’t need an abstract method in an abstract class.

The restrictions are:

• If a class has an abstract method, property, index, or event then the class must also be abstract.
• You can’t instantiate an abstract class.

There is no requirement that abstract classes must have abstract methods.
