Interfaces are like contracts: when a class implements an interface, it promises to implement the methods that are in the interface, an Abstract class in like a glorified interface, as it can do the same as the interface, but it also can implement its own methods, the down side of Abstract classes is that your class can only inherit from one other class (be it abstract or not) so Better to go with the interface, as your class can implement as many interfaces you want!
