Answer Posted / supriyo pal
There are three main differences between an interface and an abstract class:
• At the same time multiple interfaces can be implemented, but only extend one class
• an abstract class may have some method implementation (non-abstract methods, constructors, instance initializers and instance variables) and non-public members
• abstract classes may or may not be a little bit faster
