Yeah the title pretty much describes the question.
Are there any advantages to non allowing multiple inheritance in a programming language?

Why there is no multiple inheritance in Java, but implementing multiple interfaces is allowedTiny– Tiny2014-02-07 09:22:46 +00:00Commented Feb 7, 2014 at 9:22

It removes the possibility of the so called "diamond problem" (http://en.wikipedia.org/wiki/Multiple_inheritance#The_diamond_problem) that can occur when a class inherits from two classes having different implementations of methods of the same name.
Java instead have interfaces. A class can implement any number of interfaces and you can use a reference of the interface type to refer to any object of a class that implements this interface. Interfaces does not contain implementations and cannot be instantiated.
