Can one abstract class extend another abstract class and increase functionality

Question

I have an abstract class. I want to extend the abstract class by another abstract class and then implement the extended abstract class. Is it possible .If yes, whether it\'s a g

Answer 1

Yes, it is possible, and I don't see a reason not to use it if you need it (disclaimer: but however there are many ways to misuse this, and to over-complicate things, as with everything in programming usually).

One thing to notice is that the second abstract class doesn't need to implement abstract methods from first class, but the first concrete must implement both.
