VectorExample.java
import java.util.Vector;

/*
 *  Example of removeElement(Object obj) method. 
 */
public class VectorExample
{
    public static void main( String[] args )
    {
        Vector<Integer> vector = new Vector<Integer>();

        vector.add(100);
        vector.add(200);
        vector.add(300);
        vector.add(400);

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

        /*
         * Removes the first (lowest-indexed) occurrence of the argument from
         * this vector. If the object is found in this vector, each component in
         * the vector with an index greater or equal to the object's index is
         * shifted downward to have an index one smaller than the value it had
         * previously. 
         * 
         * This method is identical in functionality to the
         * remove(Object) method (which is part of the List interface).
         */

        Integer element = 300;
        boolean isRemoved = vector.removeElement(element);

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

    }
}

Output
vector  : [100, 200, 300, 400]

isRemoved  : true
vector  : [100, 200, 400]
