interface

[aparna rudra]

hii
the other question here.

all interfaces are abstract, am i right?

then how can it be instantiated, n the code here is valid?

interface IFace{}


class CFace implements IFace{}

class Base{}

public class ObRef extends Base{

public static void main(String argv[]){

ObRef ob = new ObRef();

Base b = new Base();

Object o1 = new Object();

IFace o2 = new CFace();

}}


o1=o2

b=ob

o1=b
and if i insert these lines here all are valid how can ol=o2?

Check out this tutorial I wrote once upon a time. It probably has a lot more information than you need, but the answer to your question is there, as well. At the very least, I hope it's a useful read.
