Program Code: (VectorProg.java) 

import java.util.Vector; import java.util.Enumeration; public class VectorProg {    public static void main(String args[]) {       Enumeration e;       Vector months = new Vector(3,2);       System.out.println("Initial size: " + months.size());       System.out.println("Initial capacity: " + months.capacity());            months.add("Jan");       months.add("Feb");       months.add("March");       months.add("April");       months.add("May");       System.out.println("size: " + months.size());       System.out.println("capacity: " + months.capacity());       months.add("June");       months.add("July");       months.add("Aug");       months.add("Sept");            System.out.println("size: " + months.size());       System.out.println("capacity: " + months.capacity());       months.add("Oct");       months.add("Nov");       months.add("Dec");       System.out.println("size: " + months.size());       System.out.println("capacity: " + months.capacity());            e = months.elements();            while (e.hasMoreElements()) {          System.out.println(e.nextElement());       }    } }
