1. interface contains methods that must be abstract;
abstract class may contain concrete methods.
2. interface contains variables that must be static and
final; abstract class may contain non-final and final variables.
3. members in an interface are public by default,
abstract class may contain non-public members.
4. interface is used to "implements"; whereas abstract
class is used to "extends".
5. interface can be used to achieve multiple inheritance;
abstract class can be used as a single inheritance.
6. interface can "extends" another interface, abstract
class can "extends" another class and "implements" multiple
interfaces.
7. interface is absolutely abstract; abstract class can
be invoked if a main() exists.
8. interface is more flexible than abstract class because
one class can only "extends" one super class, but
"implements" multiple interfaces.
9. If given a choice, use interface instead of abstract
class.
