Java : Collection Framework : Vector (Add Group of Objects in the Specific Index Position)


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]
