VectorExample.java
import java.util.ArrayList;
import java.util.Vector;

/*
* Example of addAll(int index, Collection<? extends E> c) method
*/

public class VectorExample
{

public static void main( String[] args )
{
Vector<Integer> vector = new Vector<>();

vector.add(10);
vector.add(20);
vector.add(30);

System.out.println("vector : " + vector + "\n");

ArrayList<Integer> arrayList = new ArrayList<Integer>();
arrayList.add(400);
arrayList.add(500);

System.out.println("arrayList : " + arrayList + "\n");

/*
* Inserts all of the elements in the specified Collection into this
* Vector at the specified position. Shifts the element currently at
* that position (if any) and any subsequent elements to the right
* (increases their indices). The new elements will appear in the Vector
* in the order that they are returned by the specified Collection's
* iterator.
*/

boolean isAdded = vector.addAll(2, arrayList);

System.out.println("isAdded : " + isAdded);
System.out.println("vector : " + vector + "\n");

}
}

Output
vector  : [10, 20, 30]

arrayList : [400, 500]

isAdded : true
vector : [10, 20, 400, 500, 30]
