Re: Programming to an Interface

I never ever use the abstract keyword in Java and I never use
implementation inheritance either (note that Java's creator
emitted regrets not having gone "pure interface" [sic]). This at
least shows that it's possible to completely bypass implementation
inheritance when programming in Java.

Yes, it's possible to avoid using abstract; and without multiple inheritance there is considerable reason to avoid abstract. But I still use it. Every so often I get into a jam where I wish I could multilply inherit, or pull all my methods up to an interface. But these events are rare, and manageable. For the most part, abstract classes are very useful beasts.
