When should we declare a class as abstract?

I know the basic concepts of abstract class.

What ever we do through abstract class, the same thing we can do through a normal class. Then why we require one more?

Mark this as answer, if it is.....

With regards

0	Explaining In general language: Generally when you want to put some basic functionality to be implemented by your child or derived classes you will create an Abstract class and then let them Fulfill those "must inherit" classes's must implement methods along with other behaviours of that class. I hope it may give you the base when u must use it. Best Regards, Puneet Sharma - Infosys Pune, India Nishithraj, if this helps please login to Mark As Answer. \| Alert Moderator
