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

/*
 *  Example of removeAll(Collection<?> c) method.
 */
public class VectorExample
{
    public static void main( String[] args )
    {
        Vector<Integer> vector = new Vector<Integer>();

        vector.add(20);
        vector.add(30);
        vector.add(40);
        vector.add(50);

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

        ArrayList<Integer> arrayList = new ArrayList<Integer>();
        arrayList.add(20);
        arrayList.add(40);

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

        /*
         * Removes from this Vector all of its elements that are contained in
         * the specified Collection.
         */

        boolean isRemoved = vector.removeAll(arrayList);

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

    }
}

Output
vector  : [20, 30, 40, 50]

arrayList  : [20, 40]

isRemoved  : true
vector  : [30, 50]
