TAILIEUCHUNG - Lecture Object Oriented Programing - Chapter 10: Object-Oriented Programming: Polymorphism

In this chapter you will learn: The concept of polymorphism, to use overridden methods to effect polymorphism, to distinguish between abstract and concrete classes, to declare abstract methods to create abstract classes, how polymorphism makes systems extensible and maintainable, to determine an objects type at execution time. to declare and implement interfaces. | 10 Object-Oriented Programming: Polymorphism One Ring to rule them all, One Ring to find them, One Ring to bring them all and in the darkness bind them. John Ronald Reuel Tolkien General propositions do not decide concrete cases. Oliver Wendell Holmes A philosopher of imposing stature doesn’t think in a vacuum. Even his most abstract ideas are, to some extent, conditioned by what is or is not known in the time when he lives. Alfred North Whitehead Why art thou cast down, O my soul? Psalms 42:5 OBJECTIVES In this chapter you will learn: The concept of polymorphism. To use overridden methods to effect polymorphism. To distinguish between abstract and concrete classes. To declare abstract methods to create abstract classes. How polymorphism makes systems extensible and maintainable. To determine an objects type at execution time. To declare and implement interfaces. Introduction Polymorphism Examples Demonstrating Polymorphic Behavior Abstract .
