I think if you have basics knowledge of any OO language then you should be aware of basic definition of Interface and Abstract class.
Here I am going to explain when to use Interface and when to use Abstract class.
Abstract class:-> If you have a common functionality that is used by its subclasses then put that method in super abstract class(now you need not to define that common method in every subclass again and again) This is what you can't do with Interface(because all the methods are by default abstract).
Interface:-> If you don't have the scenario as I discussed above(in abstract class)then choose Interface.And you can also achieve multiple inheritance using Interface that is not possible in case of Abstract class.
