Can we instantiate Interfaces?..

Answer / dhawal

answer no 1. is correct programatically but actually
instantiates means obtain the behavier of object we can do
this only by creating object of class ,object has state and
behaviour, in answer 1,we transfer state first and then
write behaviour in the class,then instantiate that class ie
like dynamic method dispatch.means therotically we can not
instantiate Interfaces

Can we instantiate Interfaces?..

Answer / anil pusuluri

One can't instantiate an interface. One can get a reference
to an interface.

Let's say Class A implements interface iA then we can't
instantiate IA
like IA a = new IA() -- this gives compilation error.

but we can get the referance to interface as below

IA a = new A()

Answer / nagendra prasadu gandla

Yes you can instanciate but you have to implement the
methods of interface at the time of instanciation itself.

EX:
interface X
{
void abc();
}
class a
{
X z=new X(){void abc(){return;}};
}
