import java.util.Vector;

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

        vector.add(50);
        vector.add(100);
        vector.add(150);
        vector.add(200);

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

        /*
         * Deletes the component at the specified index. Each component in this
         * vector with an index greater or equal to the specified index is
         * shifted downward to have an index one smaller than the value it had
         * previously. The size of this vector is decreased by 1. 
         * 
         * The index must be a value greater than or equal to 0 and less than the current size
         * of the vector.
         * 
         * This method is identical in functionality to the remove(int) method
         * (which is part of the List interface). Note that the remove method
         * returns the old value that was stored at the specified position.
         */

        vector.removeElementAt(2);

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

    }
}

Output

vector  : [50, 100, 150, 200]

vector  : [50, 100, 200]
