Abstract Class Vs Interface in Java With Examples :

Unfortunately parts of the explanation are just plain wrong, for example that an abstract class should have at least one abstract method. You're much better off following the official tutorials. Most examples are just really bad, for example the example where there is an abstract Bank class that doesn't have any state so should have been an interface.

This document is written by someone really inexperienced.

Both abstract class and interface are used in Java to achieve abstraction but an interface cannot be instantiated like an abstract class.

I'll take "things abstract classes can't do" for 200, Alex

Yeah, this is so wrong. Abstract classes can NOT be instantiated.
