If a class implements an interface and does not provide method bodies for all Let's consider the example of vehicles like bicycle, car, bike ,they have.

The topic of today's class is interfaces: separating the interface of an abstract data type . We should strongly consider revising the implementation. . Code that doesn't call mutators can be written to work automatically with either kind of list. In particular, a class which implements a member of an interface is not considered to have inherited that member. Again, is this confusing? Yes. However, not every class needs an interface, and not every interface makes sense. I thought it would be useful to enumerate some good.
