Abstraction - Interfaces are the best examples of
abstraction .
Encapsulation - Classes are best examples of encapsulation.
Generally we encapsulate what varies &
we abstract commonalities...
One more thing, You should always subclass for behabiours..
you should never subclass for properties / attributes. If
only properties vary, then you have got to encapsulate them
in somewhere else e.g. in a class or in some collection
object like - Properties in Java / Map
Hope this helps..
