Multiple Inheritance is a feature of C++ where a class can inherit from more than one classes. The constructors of inherited classes are called in the same order in which they are inherited. For example, in the following program, B’s constructor is called before A’s constructor. 1#include...
Inheritance is one of the fundamental principles of Object-Oriented Programming (OOP) that allows one class (the child class or subclass) to inherit fields and methods from another class (the parent class or superclass). This promotes code reuse, modularity, and better maintainability. In this a...

1. What is Multiple Inheritance? In multiple inheritance, a child class can inherit the behavior from more than one parent classes. Note that a Java class can implement multiple interfaces, but an interface does not define concrete behavior rather, interfaces are used for defining the contracts ...
In this lesson, we will explore the concept of multiple inheritance, and the reasons that Java does not support this object-oriented principle...
