package com.tutorialspoint;

import java.util.Vector;

public class VectorDemo {
   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);

      // set 15 at 2nd index position
      vec.set(2,15);

      // let us print all the elements available in vector
      System.out.println("Added numbers are :- "); 
      
      for (Integer number : vec) {         
         System.out.println("Number = " + number);
