Inheritance, Polymorphism, and Extending Classes

  • Wallace Wang


In  Chapter 11 you learned how objects were created from classes and how classes define properties and methods. To protect its data and methods from other parts of a program, an object isolates or encapsulates its code. Encapsulation is one prime advantage of object-oriented programming because it creates self-contained code that you can easily modify or replace without affecting any other part of a program.
