I normally used this “What is the difference between an Abstract Class and an Interface” as a quick way to gauge someone. Lots of times, its the first or second question I will ask. I cannot tell you how many times people will mess this question up. 9 times out of 10, people read about it at some www.basicinterviewquestions.com...

I normally used this “What is the difference between an Abstract Class and an Interface” as a quick way to gauge someone. Lots of times, its the first or second question I will ask. I cannot tell you how many times people will mess this question up. 9 times out of 10, people read about it at some www.basicinterviewquestions.com (not a real site hehe), giving the canned response of “You can define default functionality in an abstract class and you can just define functions in an interface”. The curve ball is thrown when you ask “Why would you use one over the other?”. That will earn you the ‘deer in headlights’ look. The other 1 out of 10 you will get a “I never had to use that so I don’t know”. At the top level, the are a few basic difference. Abstract classes allow for default default function definition. This means that whatever class extends the abstract class will have access to this. If we have a base class where all the classes will perform the same function, then we can define that in our Abstract class. An interface is a list of functions or properties that if a class implements it, it will have to have those functions defined within it. It is a situation of “Is-A” vs “Can-Do-this”. Objects that extends an Abstract class “Is-A” base class. Objects that implement “Can-Do-This”. Now if I asked this question and got the answer, yes, that would be the correct answer. However, I want to know why one would want to use an interface over an abstract class, and vice versa. read less
