Hello Emerald,

I have read your concern regarding multiple inheritance in Java. As what I have understood, you wanted to know if it’s possible to use multiple inheritance in Java from two different classes. Is it right?

In the first place, java is designed for single inheritance; the creator omitted multiple inheritance per se. Its single inheritance doesn’t usually show a problem; when in fact, multiple inheritance could be a sign of bad design. However, developers found ways to successfully accumulate multiple inheritance in Java and solve the problem. In particular, separately rooted hierarchy with object as the definitive ancestor of all classes and Java solve this issue through C++ in multiple inheritance. Some people think that MI only causes chaos and has very little benefit. Nevertheless, minimal condition shows that multiple inheritance is very useful. It can also be benefited as a refinement of an interface.

I hope I am in the right track of understanding your concern and gave you a hand to fix the problem. I hope this information is of good help.

Good Luck!

Regards,

Mali

Hello Emerald Hilton,

Java doesn't support Multiple inheritance. It only supports Single and MultiLevel inheritance. Developers intentionally removed this functionality to tackle some problems such as "Diamond Problem of Multiple Inheritance".

 

But, there is another way of achieving Multiple Inheritance, through the use of Interface. A class can implement multiple interfaces.

 

In your case, make sure that all important functions you now defined in the classes are defined in the interfaces and you can implement multiple interfaces to your child class.

Hope it helps
