Java Tutorials - 51 Abstract Classes

In this video we are going to learn about abstract classes. Typically, a class is declared abstract when at least one method in the class is abstract. If a class does contain at least one abstract method, the class must be declared as abstract. A class that inherits from an abstract class, without defining all the abstract methods of the parent class, must also be declared an abstract class. Objects can not be instantiated from abstract classes. For more information on abstract classes: https://docs.oracle.com/javase/tutorial/java/IandI/abstract.html
