Interface should be preferred over inheritance because interfaces increase code reusibility, decreases coupling and reduces the chances of breaking of sublasses dude to change in superclass

we use inheritance to extend the behavior of an object while interfaces are used to implement behaviors from one or more than one object (multiple inheritance in c++)

I think the primary reason for making a choice between inheritance and interface is to make the distinction of having default behavior of the object.

In inheritance, the child class extends the parent class's behavior as the default and this is the case for all other subclasses of that parent class.

In interface, you are simply defining a common set of operations that may be entirely different depending on the implementation.

what is "subclass dude" ??? @ashwini manny on August 14, 2009

inheritance is more useful over interface when it comes to reusability , isn't it?
