Thread: Interface Vs Abstract class

I am last year MCA student. Currently I am learning object oriented programming (OOPS) concept. I am confused between interface and abstract class. Also I want to know difference between an Interface and an Abstract class. I am not getting any perfect answer. Please reply me as soon as possible.

Difference between Interface and Abstract class

• Abstract class defines only some or none of the methods, but interface defines all the methods.

• In Abstract Class as a minimum one method is undefined whereas in interface all method is undefined

• Abstract Class s not comes in inheritance but interface come in inheritance chain.\

• Abstract classes are faster than interfaces.
