CHAPTER 6 CHAPTER 6 Understanding Inheritance Inheritance is one of the most important benefits of object-oriented programming. It allows a new class to be written that extends an existing class. This chapter discusses the details of understanding and implementing inheritance, including the is a relationship, the extends keyword, the Object class, method overriding, the super keyword, and how inheritance affects constructors. An Overview of Inheritance In object-oriented programming (OOP), a new class can be built upon an existing class with the new class extending the existing class and inheriting its attributes and behaviors. Extending a class is called inheritance. The existing class is referred to as the parent class, and the new class is referred to as the child class. Other common OOP terms for the parent class are base class and super class. The child class is often referred to as the derived class or subclass. These different terms for the parent and child class are used interchangeably but have the same meaning.
