One - This forum ( ORM ) is not the correct one to post this question
Two - demanding answers will get you nowhere
However to get trhe ball rolling and also to induce much more knowledgable people to correct me - will give it a shot .
The simplest of reasons is related to multiple inheritance
( and I am sure you are looking for more than this )
Another difference I can think of is if you have some default generic behaviour to implement - go for an abstract class - since interface will not allow implementations
One more - ( this is my understanding ) - if the system changes a lot I think its better to have an abstract class as supertype where - you can add a "new" method with some default implementation .
If this were to be an interface - it would be a maintenance nightmare to add a new method .

ask on javaranch.
Millions saw the apple fall, but Newton asked why.
If you understand, say "understand". If you don't understand, say "don't understand". But if you understand and say "don't understand". How do I understand that you understand? Understand!
I agree. Here's the link:
