Hi,
I am little bit confused about interface and abstract.
I found this question in onesite.
8) What is the difference between interface and an abstract class?
Ans : All the methods declared inside an Interface are abstract. Where as abstract class must have at least one abstract method and others may be concrete or abstract.
*I checked WindowListener interface in
java API, but i didn't
get any abstract method. I think abstract keyword should be
written before the method.
Can anyone clarify that,
