Inheritance & Abstract Classes
Every class inherits (implicitly) from the Object class in Java. • Every class is-a Object. • There are no fields in Object but there are.
Abstract classes vs. Interfaces
The class containing an abstract method MUST be qualified as abstract. • An abstract method must be Java does not support multiple inheritance.

Abstract classes Interfaces & Comparators
An abstract class should have at least one abstract method. a class or an abstract class. ? In Java multiple inheritance is achieved using interfaces.
Abstract Method & Abstract Classes
In Java 8 you have to do more work than this. Page 14. Other Examples of Abstract Classes. An interface specifies required behavior.
