TAILIEUCHUNG - Lecture Object Oriented Programing - Chapter 9: Object-Oriented Programming: Inheritance

In chapter 9 you will learn: How inheritance promotes software reusability, the notions of superclasses and subclasses, to use keyword extends to create a class that inherits attributes and behaviors from another class, to use access modifier protected to give subclass methods access to superclass members, to access superclass members with super, how constructors are used in inheritance hierarchies. | 9 Object-Oriented Programming: Inheritance Say not you know another entirely, till you have divided an inheritance with him. Johann Kasper Lavater This method is to define as the number of a class the class of all classes similar to the given class. Bertrand Russell Good as it is to inherit a library, it is better to collect one. Augustine Birrell Save base authority from others books. William Shakespeare OBJECTIVES In this chapter you will learn: How inheritance promotes software reusability. The notions of superclasses and subclasses. To use keyword extends to create a class that inherits attributes and behaviors from another class. To use access modifier protected to give subclass methods access to superclass members. To access superclass members with super. How constructors are used in inheritance hierarchies. The methods of class Object, the direct or indirect superclass of all classes in Java. Introduction Superclasses and Subclasses protected .
