If you are curious asking me why doesn't java allow multiple inheritance, think about this scenario. Let us say the Automobile Class has a drive() method and the Car class has a drive() method and the Ferrari class has a drive() method too. Let us say you create a new class FerrariF12011 that looks like below:
Public class FerrariF12011 extends Ferrari, Car, Automobile {…}
And at some point of time you need to call the drive() method, what would happen? Your JVM wouldn't know which method to invoke and you may have to instantiate one of the classes that you already inherit in order to call its appropriate method. Sounds confusing right? To avoid this nonsense is why the creators of java did not include this direct multiple inheritance feature.

What does java not support?
Java does not support multiple inheritance.......
Can we implement multiple inheritance in java using package and interface?
Yes. Java does not support full fledged/proper multiple inheritance. But, whatever partial inheritance that Java supports can be implemented using interfaces 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.
How can you write multiple inheritance program in java?
Java does not support direct multiple inheritance. You can implement partial multiple inheritance using interfaces. ex: public class ExMultInherit implements interface1, interface2, interface 3 { ... .... ...... }
How do you achieve multiple inheritence using class in java?
Multiple Inheritance cannot be achieved only by using Classes in Java. You would have to use Interfaces as well to achieve multiple Inheritance. Java as such does not support direct multiple inheritance. We can have theoretical multiple inheritance by using interfaces using which you can outline the kind of functionality your child classes can have. For example you can have a declaration like this public class A implements X, Y, Z { } Here this class A would have to implement the methods that are declared in the interfaces X, Y & Z. So the outline of the functionality that A would have can be found by checking the interfaces but the exact implementation would depend on the programmer who codes class 'A'
Give the structure of multiple 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.
What is ambiguity in multiple inheritance?
Java does not support multiple inheritance
What is problem in multiple inheritance?
Java does not support direct multiple Inheritance. Harder to implement, not every language support it: C++ does, Java does not.
What do you mean by multithread program in java?
A Program in Java that spawns multiple threads is called a multithreaded program in Java.
Can a single Java class subclass extend both InputStream and Reader. True or False?
Java does not have multiple inheritance, so no. Java can use multiple interfaces, though, with the "implements" keyword.
How do you control PowerPoint slides using java?
You can control Powerpoint Slides using Java with Aspose.Slides for Java Library: - http://www.aspose.com/java/powerpoint-component.aspx
What are the technologies without using java?
you can use type writer to avoid using java :)
What are the alternatives to inheritence in java?
Java does not support multiple inheritance; a subclass cannot have more than one parent. Java compensates for this with interfaces. A class can implement multiple interfaces, but can only extend one class.
