1 - Introduction

Inheritance in Java is a process in which a class acquires the properties (attributes and methods) of another Java class. With the use of inheritance, data and information are managed in a well organized and structured hierarchical order.
The class that inherits the properties of another class is called the subclass (derived class or daughter class) and the class whose properties are inherited is called superclass (base class, parent class, parent class ...).
