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

/*
 *  Example of addAll(Collection<? extends E> c) method 
 */
public class VectorExample
{

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

        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");

        /*
         * Appends all of the elements in the specified Collection to the end of
         * this Vector, in the order that they are returned by the specified
         * Collection's Iterator
         */
        boolean isAdded = vector.addAll(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, 30, 400, 500]
