Java Vector iterate via Iterator

Introduction

To iterate Vector via Iterator in Java 

Iterator<Integer> vItr = v.iterator(); 
    
System.out.println("\nElements in vector:"); 
while(vItr.hasNext())  
  System.out.print(vItr.next() + " ");

import java.util.Iterator;
import java.util.Vector;

public class Main {
  public static void main(String args[]) {

    // initial size is 3, increment is 2
    Vector<Integer> v = new Vector<Integer>(3, 2);

    System.out.println("Initial size: " + v.size());
    System.out.println("Initial capacity: " + v.capacity());

    v.addElement(1);/*from  www  .  j  a va  2  s  . c  om*/
    v.addElement(2);
    v.addElement(3);
    v.addElement(4);

    Iterator<Integer> vItr = v.iterator(); 
    
    System.out.println("\nElements in vector:"); 
    while(vItr.hasNext())  
      System.out.print(vItr.next() + " ");
