Multiple inheritance in java

Answer 1

Actually, java does not support multiple inheritance. You can achieve partial multiple inheritance using interfaces but java is not like C or C++ where you can do direct multiple inheritance. However, you can achieve partial multiple inheritance with the help of interfaces.

Ex: public class FerrariF12011 extends Ferrari implements Car, Automobile {

Answer 2

Should be "Inheritance", not "Ineritance".

public class Dog{

private String notInherited;

protected String name = "Spike";

public String species = "dog";

}

public class Greyhound extends Dog{

private String type = "Greyhound";

}

Of the two classes above, Greyhound inherits from Dog. Since it inherits from dog, Greyhound also inherits the protected field name and the public field species that you just don't see in the Greyhound class, but it does not inherit the private field notInherited.

Answer 3

Java does not support direct multiple inheritance. A class in java can extend only one class. But java supports partial multiple inheritance that can implemented using Interfaces. An interface is a skeleton class that can decide the functionality of the class that implements it. There is no restriction about the number of Interfaces a class can implement and hence by implementing interfaces from a class, we can achieve indirect or partial multiple inheritance.

Answer 4

Actually, java does not support multiple inheritance. You can achieve partial multiple inheritance using interfaces but java is not like C or C++ where you can do direct multiple inheritance. However, you can achieve partial multiple inheritance with the help of interfaces.

Ex: public class FerrariF12011 extends Ferrari implements Car, Automobile {…}

And this is under the assumption that Car and Automobile are interfaces.

Here if you see, though you don't inherit concrete code from the Car or the Automobile interface, you do inherit skeleton methods that determine the way your class eventually behaves and hence this can be considered partial Multiple Inheritance

Answer 5

No, Java does not allow multiple inheritance. However you can often get similar functionality by implementing multiple interfaces or by using aggregation.

Answer 6

Yes.
