66.Vector in JAVA

//Vector is like the dynamic array which can grow or shrink its size.

Unlike array, we can store n-number of elements in it as there is no size limit. 

import java.util.*;

class vector_class

{

public static void main(String[] args) {

Vector v = new Vector();

System.out.println("Vector = " + v);

System.out.println("Vector Capacity = " + v.capacity());

System.out.println("Vector Size = " + v.size());

v.add("one");

v.add("two");

v.add("three");

System.out.println("\nVector = " + v);

System.out.println("Vector Capacity = " + v.capacity());

System.out.println("Vector Size = " + v.size());

for (int i = 1; i <= 10 ; i++ ) {

v.add(i);

}
