Hi, In an interview I have been asked a question What is the'Well known abstract class without methods'? Please tell me, I dont know the answer for this.
Hmmm.. I had heard about few marker interfaces flying around like the java.io.Serializable interface which do not declare any methods. The abstract classes with no interfaces are called marker classes, but can't site you any example of such an interface.
My question is very clear, I am not asking about Marker/Tagged interface. "Very familiar abstract class which doesn't have any(abstract/concrete) methods". I think now it is clear.
Don't get me started about those stupid light bulbs.
