What are Abstract Classes and how Different are they from Interfaces?

The video tutorial explains the concept of abstraction in Java, focusing on abstract classes and methods. It provides a real-life example using aircraft construction rules to illustrate how abstraction works. The tutorial also covers the implementation of abstract methods in child classes and compares abstract classes with interfaces, highlighting their differences and similarities.
