import java.util.Vector;

public class Main {
   public static void main(String[] args) {
           
      Vector<Integer>  vec = new Vector<Integer> (4);
      
      Integer anArray[]=new Integer[4];
      
      anArray[0] = 100;
      anArray[1] = 100;
      anArray[2] = 100;
      anArray[3] = 100;

      
      vec.add(4);
      vec.add(3);
      vec.add(2);
      vec.add(1);
      
      for (Integer number : anArray) {         
         System.out.println("Number = " + number);
      }
      
      // copy into the array
      vec.copyInto(anArray);
      
      for (Integer number : anArray) {         
         System.out.println("Number = " + number);
      }                
   }
