Answer Posted / rod
the bowlingball example I put is when you combine the
abstract class ball with the interface bowlable .. a poor
example perhaps.. lets replace that with
a sock may implement a washable interface which can also be
implemented by cars, shirts, dishes... etc.. so why bother
with this. The reason is for future use as the system grows.
It is more likely that you will run into an object that
needs to be 'washed' then you can in fact call this method
without knowing the lower level details.
its more than just organising things that do or are acted
upon by the same conceptual action. It means that later you
can just use the method because the interface populates the
list of things you can choose from at code completion in the
editor ..for example.
