tailieunhanh - Lecture Object Oriented Programing - Chapter 8: Classes and Objects: A deeper look

In this chapter you will learn: Encapsulation and data hiding, the notions of data abstraction and abstract data types (ADTs), to use keyword this, to use static variables and methods, to import static members of a class, to use the enum type to create sets of constants with unique identifiers, how to declare enum constants with parameters. | 8 Classes and Objects: A Deeper Look Instead of this absurd division into sexes, they ought to class people as static and dynamic. Evelyn Waugh Is it a world to hide virtues in? William Shakespeare But what, to serve our private ends, Forbids the cheating of our friends? Charles Churchill This above all: to thine own self be true. William Shakespeare Don’t be “consistent,” but be simply true. — Oliver Wendell Holmes, Jr. OBJECTIVES In this chapter you will learn: Encapsulation and data hiding. The notions of data abstraction and abstract data types (ADTs). To use keyword this. To use static variables and methods. To import static members of a class. To use the enum type to create sets of constants with unique identifiers. How to declare enum constants with parameters.
