An abstract class allows polymorphism as well. Not sure why you have it specific to interfaces. To my knowledge, inheriting from multiple classes has nothing to do with polymorphism.

Indeed you have done a good job on differentiating the interface and abstract class in java . just to add when we use abstract class we can not extend another class but with interface we have that space spare with us. just consider if Runnable were an abstract class instead of interface, how inflexible it would be.

"The code that we use to love, now doesn't look as rosy anymore." << The speaker's line was so sweet : )

Yes Ron, but it was a costly learning curve to me, I had to pay such a huge time for that : (

@Fajar I was listening to an interesting podcast about legacy code. And the speaker raised something that I found very simple yet profound.

Legacy code is about perception. As soon as one reaches the next level of craftmanship, suddenly we look back and see our code in a different way. The code that we use to love, now doesn't look as rosy anymore.

But hey, that's the process of learning, right?

I got this feeling for the first time when I tried to get “Favor composition over inheritance” line from Head First Design Patterns. That means, I even need more than a year to grasp it, how pathetic…
