Inheritance does execute the IS – A relationships.
Types of Inheritance

In it, you will come across only single superclass as well as merely single subclass by which is meant they have got communication amid them on the one to one basis.
Multilevel inheritance
A derived class may as well be inherited by another class which means within the When a Derived class once more shall be inherited by another class after that produces multiple levels.
Multiple inheritances
Multiple inheritances make that wherein a class inherits the facets from among two base classes as the derived class gets facets from two base classes.
Hierarchical inheritance
Hierarchical inheritance forms that wherein the base class has got a lot of subclasses or as the base class is utilized or may be inherited via numerous subclasses.
Hybrid inheritance
It can be said to be a mixture of more than two or more inheritance, and within the inheritance, you will find a code encloses two or maybe three kinds of inheritance within one single code.
