Java Video 20: Inheritance | Abstract | Overloading | Overriding

In this video you will learn what inheritance is. How to extend a class. the various types of inheritance. Abstract classes. Method overriding and overloading. Inheritance in Java allows a class developer programmer to efficiently build one class from another class. Rather than having to "re-invent the wheel", a class developer can take advantage of the methods in one class and automatically include them in another class plus add some more of his/her own methods. The new class that is based upon the original class is called a child class (aka subclass or derived class). The original class is known as the parent class (aka superclass or base class). We can classify the inheritance into the five types. These are: Single Inheritance Multilevel Inheritance Multiple Inheritance Hierarchical Inheritance Hybrid Inheritance Other videos: Video1: How to Install NetBeans with JDK Cobundle. https://www.youtube.com/watch?v=ctIiu​​...
