In this lecture we will learn:
Types of inheritance in Java
Single inheritance in Java
Multilevel inheritance in Java
Examples related to single and multilevel inheritance
Single Inheritance:-
In single inheritance, subclasses inherit the features of one superclass.
Only one parent class exists in single inheritance.
It is when there are only two classes.
e.g.,
Calc class inherits the properties of AdvCalc class.
Here, Calc - child class
AdvCalc - parent class
Multi-level inheritance:-
In Multilevel Inheritance, a derived class will be inheriting a base class, and as well as the derived class also acts as the base class for other classes.
More than one parent class exists in multilevel inheritance.
It is when we have multiple layers in between the classes.
e.g.,
Calc class inherits the properties of AdvCalc and further AdvCalc inherits the properties of VeryAdvCalc.
Here, Calc - child class
AdvCalc - parent class of Calc & child class of VeryAdvCalc
VeryAdvCalc - parent class of both other classes
