Why Java Doesn’t Support Multiple Inheritance

In this tutorial, we are going to see why multiple inheritance is not supported in Java. In Java, a class cannot inherit multiple classes. Therefore, multiple inheritance is prohibited.
 

Example :

public class A extends B, C { ... }

However, a class can implement one or more interfaces, which makes it possible to replace multiple inheritance.
 

 
The reason behind this is to avoid any ambiguity.

Consider a case where class A inherits from class B and class C. Classes B and C have the same show() method.
 

 
Now, the Java compiler cannot decide which show() method it should inherit. To avoid ambiguity, multiple inheritance is not supported in Java.
