Interfaces are 100 % abstract classes.They cannot be instantiated.Their sole purpose is to be implemented.So why does the following code works just fine while it is attempting to instantiate an interface.


Please correct me if I am wrong!

On a side note....

Interfaces are 100 % abstract classes.


is not entirely accurate because there are some differences between abstract classes and interfaces.
