}

class Medium extends Large {
public void Print() {
super.Print();
System.out.println("This is medium");
}
}
class Small extends Medium {
public void Print() {
super.Print(); ;
System.out.println("This is small");
}
}


class Question43 implements ExtraLarge{
public void display(){
System.out.println(extra);
}
public static void main(String[] args) {
Small s = new Small();
s.Print();
Question43 q = new Question43();
q.display();

}
}
