Multiple inheritance in C# In C#, the classes are only allowed to inherit from a single parent class, which is called single inheritance. But you can use interfaces or a combination of one class and interface(s), where interface(s) should be followed by class name in the signature.
C is not object-oriented -- you can't even use single inheritance let alone multiple inheritance.
Java does not support multiple inheritance
C++ allows multiple inheritance while Java does not. In my opinion, multiple inheritance is not useful because it can get very confusing very quick. For polymorphism, C++ does early binding by default, while Java does late binding by default. Late binding is more useful than early binding.
Single Inheritance Multiple Inheritance Multilevel Inheritance
Java doesn't have multiple inheritance proper. It is possible for a class to implement different interfaces - however, in this case, only the method names are "inherited", not their contents. It is also possible to use composition instead of inheritance: an object can contain objects of different classes, and use the methods of the objects it contains - but this, too, is a different mechanism than inheritance.
Types of dominance, multiple alleles, sex linked inheritance, polygenic inheritance and maternal inheritance.
Java does not support multiple inheritance. It is done with the help of interfaces in java. a class can implement n number of interfaces, thus showing multiple inheritance. but a class cannot extend multiple classes in java.
Java does not allow the multiple inheritance of concrete classes, though it does allow a "hybrid" inheritance of one concrete class and multiple interfaces.
Java does not support direct multiple inheritance. You can implement partial multiple inheritance using interfaces. ex: public class ExMultInherit implements interface1, interface2, interface 3 { ... .... ...... }
There are no drawbacks to multiple inheritance if multiple inheritance is precisely what is required to achieve your goal. If there are any drawbacks then it is only because of poor design, not multiple inheritance itself. For instance, when designing classes to simulate vehicles, an amphibious vehicle would inherit the properties of both an off-road vehicle and a marine vehicle, therefore multiple inheritance would be an appropriate usage.
Java does not support direct multiple Inheritance. Harder to implement, not every language support it: C++ does, Java does not.
