The Java programming language supports multiple inheritance of type, which is the ability of a class to implement more than one interface. ... As with multiple inheritance of implementation, a class can inherit different implementations of a method defined (as default or static) in the interfaces that it extends.

Why multiple inheritance is not allowed in Java?

Java does not support multiple inheritance because of two reasons: In java, every class is a child of Object class. When it inherits from more than one super class, sub class gets the ambiguity to acquire the property of Object class.. In java every class has a constructor, if we write it explicitly or not at all.

How multiple inheritance is used in Java?

The only way to implement multiple inheritance is to implement multiple interfaces in a class. In java, one class can implements two or more interfaces. This also does not cause any ambiguity because all methods declared in interfaces are implemented in class.
