VectorExample.java
import java.util.List;
import java.util.Vector;

/*
 *  Example of using subList(int fromIndex,int toIndex) method remove
 *  range of elements. 
 */
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);
        vector.add(60);
        vector.add(70);

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

        /*
         * Returns a view of the portion of this List between fromIndex,
         * inclusive, and toIndex, exclusive. (If fromIndex and toIndex are
         * equal, the returned List is empty.)
         * 
         * The returned List is backed by this List, so changes in the returned
         * List are reflected in this List, and vice-versa. The returned List
         * supports all of the optional List operations supported by this List.
         */

        List<Integer> subList = vector.subList(1, 4);

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

    }
}

Output
vector  : [20, 30, 40, 50, 60, 70]

subList  : [30, 40, 50]

subList  : []

vector  : [20, 60, 70]
