What is multiple inheritance explain with example how is it achieved in Java?

When one class extends more than one classes then this is called multiple inheritance. For example: Class C extends class A and B then this type of inheritance is known as multiple inheritance. Java doesn’t allow multiple inheritance.

So in C++ multilevel inheritance, a class has more than one parent class . For example, if we take animals as a base class then mammals are the derived class which has features of animals and then humans are the also derived class that is derived from sub-class mammals which inherit all the features of mammals.

Inheritance is the mechanism to achieve the re-usability of code as one class(child class) can derive the properties of another class(parent class) . It also provides transitivity ie. if class C inherits from P then all the sub-classes of C would also inherit from P. Multiple Inheritance.

In C++ programming, a class can be derived from more than one parent . For example, A class Bat is derived from base classes Mammal and WingedAnimal . It makes sense because bat is a mammal as well as a winged animal.
