#6.3 Java Tutorial | Multiple Inheritance in Java?

In this lecture we are discussing:
1)what is multiple inheritance?
2)Why Java does not support Multiple Inheritance?
3)What is ambiguity and not allowed in java?

#1
Multiple inheritance
If a particular class inheriting multiple class then this type of inheritance is called multiple inheritance.
like c++ language there are multiple inheritance like that :
class A
{
... .. ...
};
class B
{
... .. ...
};
class C: public A,public B
{
... ... ...
};

But Java not allowed we have alternate option for that is implementing multiple interface not we will discussing in upcoming lecture.
#2
why java not support multiple inheritance?
:- Because of the Ambiguity problem, Java does not support multiple inheritances directly.

#3
Why it is ambiguous?
suppose we have some class A, B and c
class A
{
... .. ...
show(){

}
};
class B
{
... .. ...
show(){

}
};
class C extends A,B //assume for some instance java support multiple inheritence
{
... ... ...
show();
//here we get ambiguity since if we allowed multiple inheritance and same two property or method belong to class A and Class B
//then how C class use show() method there is ambiguity of choice...
//that’s why java exclude the concept of multiple inheritance

};

Very useful lesson, although I was hoping you would go in depth about implementing multiple interfaces, because it is similar to multiple inheritance of pure abstract classes in other languages like C++.

Can interface use for multiple inheritance?

[chevalierdeloccident]

Sad, it doesn't support this directly. The sensible solution would be to call the parent class method by default, bypassing the inherited "overwrites"; thereby granting the programmer the chance to overwrite the parent method for the multi inherited class.

Operator overiding ka concept ho jyga na

[atharvabhatkhalkar]

Not perfect reason! What if I don't give same methods in both class. Then I should be able to use multiple inheritance!
