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
