package poly;
interface XInterface{
public abstract void runDemo();
}
abstract class XClass implements XInterface{
String s="Java";
public abstract void runDemo();
{s="C++";}
}
public class YClass extends XClass implements XInterface{
{s = "C#";}
public void runDemo(){
System.out.println("Demo"+super.s);
}
public static void main(String args[]){
XInterface xi=new YClass();
xi.runDemo();
}
