Hi Ranchers,
Considering the code below, can anyone tell me what is the use of Interface reference variable? I mean how will it be of help when there is a class that implements that interface? Has it got anything to do with casting?
interface Sample{int j=10;}
public class Main implements Sample{
public static void main(
String [] args){
Sample joe=null;
System.out.println(Sample.j); //joe.j also prints 10???
}
}
Thanks in advance,
Regards,
Jothi Shankar Kumar. S
