Examine the methods of polymorphism, inheritance and abstraction, in Java. During this course, you will discuss inheritance in the context of a Java class hierarchy. See how to create a subclass. Override a method in the superclass. Use the SUPER keyword, to reference the superclass. Discover Polymorphism. Cast a superclass reference to the subclass type.
