import java.util.Vector;

public class Main {
    
   public static void main(String[] args) {
           
      Vector<Integer>  vec = new Vector<Integer> (4);

      
      vec.add(0,4);
      vec.add(1,3);
      vec.add(2,2);
      vec.add(3,1);

      for (Integer number : vec) {         
         System.out.println("Index :"+vec.indexOf(number) +" Number: " + number);
      }
      
      // added new number 10 at 3rd position/index
      vec.add(3,10);
      
      
      for (Integer number : vec) {         
         System.out.println("Index :"+vec.indexOf(number) +" Number: " + number);
      }
   }
