Through Interfaces.........

Mr.Firdouse,I know that it is possible through interfaces 
but i want to know how it is implemented?Can u give me a 
clear answer?

Hi, Aruna how r u doing?
  
   In Java multiple inhritance provided through interfaces 
by extending morethan one interface. We can extend more 
than one class in C++. But this is not possible in java 
that's why java doesn't support mutiple inhritance 
directly. 
public interface GroupedInterface extends Interface1,
                                        Interface2, 
Interface3 

An interface can extend other interfaces, just as a class 
can extend or subclass another class. However, whereas a 
class can extend only one other class, an interface can 
extend any number of interfaces. The interface declaration 
includes a comma-separated list of all the interfaces that 
it extends.
                 Aruna if you still not understood please 
go through

erface.html this site. if you understad it' good. give me 
feed back.
          Thanq

in java multiple inheritance is possible using interface.

In Java multiple inheritance is not Possible....
Don't think that interface is for multiple inheritance ,most
of the book given wrong idea about - interface is for 
multiple inheritance .

Multiple Inheritance is not at all posiible in Java.
Reason: Inheritance means reusability of code and 
Interfaces are just the declaration of methods not 
implementation.We have to write code for methods for the 
interface in class which is implementing that Interface.

Yes ,  Namarata U r answer is write.....!! 
I am agree with this satements .

yes, Namratha u r correct, i got u r point

multiple inheritance is not possible in java but we can 
apply the multiple inheritance concept using interfaces in 
java but it doesn't meant that java will support multiple 
inheritance rather we can implement the idea of multiple 
inheritance as follows......


    eg:

          <class name> implements <class1>,<class2>,...
            {
                }



            but the interface technique will not gives the 
exact definition of multiple inheritance.....

Namrata what i am telling is,multiple inheritence is not
possible in java.that is every body knows but the thing is,
in c++ while the time of multiple inheritance ambiguity is
happened.like if u have same methods in all extended classes
while the time execution ambiguity will happen.but in the case
of interfaces in java even though u have same methods in all
interfaces there s no ambiguity at execution.for avoiding this
ambiguity in c++ we are using virtual keyword.
 ofcourse ur correct.but internally interfaces are satisfied
the multiple interfaces concept.

See gopi what namrata said is exactly correct,
in java Interfaces r given for Polymorphism not multiple 
inheritance.
more over Inheritance means:the super class object is sub 
object to sub class,but when u going through interfaces we 
r not creating object directly. so come super class object 
is sub object to sub class object.

my conclusion is java doesn't support multiple inheritance

Hi all, This is Pradeep...
I am confused by the java statement that "By using 
interface we can achieve multiple inheritance bcoz java 
doesn't support Multiple inheritance".
Yes.Ok java doent support Multiple inheritance. Now we know 
that inheritance means that "one object acquires the 
property of another object".
So how can it is possible achieve Multiple inheritance by 
interface.
Interface that contains just undefined methods like below 
code.

interface Member1
{
public void eye();
public void nose();
public void mouth();
}
interface Member2 extends member1
{
public void neck();
public void hand();
public void stomach();
}
interface Member3 extends Member1,Member2
{
public void leg();
} 

class Man implements Member3
{
public man()
{
Member3 ref=new Man();
}
// Here Implements all 7 methods.
}


/*
Is the above code defines multiple Inheitance?
undefined methods are eye,nose,mouth,neck,handand stomach 
are fall in Interface Member3 .Yes. But Inheritance means 
that one object acquires the property of another 
object.Property means that code and data.
In here, there is no code just declarations of method which 
is not to be a code .
So How can we say interface achieve multiple inheritance.
Please any one explain and clear my doubt with simple 
example.

java does nt support multiple interface by using interfaces
its support tis one

i agree with the answer tat multiple inheritance is 
achieved by interfaces,
but the question is 

WHAT IF TWO INTERFACES HAVING SAME METHODS THEN WHAT METHOD 
IS USED IN CLASSES WHO IS IMPLEMENTING THE INTERFACES?

Yes...Gopi u r answer is right.... i am agree with u
