Abstract class: You can inherit only one class.
Interface: You can inherit more than one interface.
Abstract class: It contains both completed and uncompleted
(abstract) methods.
Interface: It only contains uncompleted methods (methods
without body).
Abstract class: Access modifiers are there for methods and
properties.
Interface: It does not have access modifier for methods or
properties. By default they are public.
Abstract class: Fast
Interface: Require more time to find actual method in classes.
Abstract class: It can contain fields and constants.
Interface: no fields can be defining in interface.
