   public static void main(String[] args) {
      // create an empty Vector vec with an initial capacity of 4      
      Vector<Integer> vec = new Vector<Integer>(4);

      // use add() method to add elements in the vector
      vec.add(4);
      vec.add(3);
      vec.add(2);
      vec.add(1);

      // let us print the element at 1st position in the vector
      System.out.println("Element at 1st position :- "+vec.elementAt(1));
