ArrayList, Iterator, save last element

Question

Hi,
I have a JPanel where a user can click with the mouse... I can save the coordinates of the mouseclicks in an ArrayList. However, I don't know how I can save the last clicked coordinate in a separate variable...
private List <Point>playerCoordinatesList = new ArrayList<Point>();
private Point playerCoordinates, playerCoordinatesOld;
Iterator i;
    protected void paintComponent( Graphics g ) {
        super.paintComponent(g);
        Graphics2D g2 = (Graphics2D) g;
        for(i = playerCoordinatesList.iterator(); i.hasNext(); ) { 
             playerCoordinates = (Point)i.next();
            g2.drawOval(playerCoordinates.x, playerCoordinates.y, OVALWIDTH, OVALHEIGHT);
    public void updatePlayerPosition(MouseEvent evt) {
        playerCoordinatesList.add(evt.getPoint());
    }Thanks!

Answer 1

Firstly, why to use Vector instead ArrayList? The only difference is that Vector is synchronized, and I cannot see the need for it.
Secondly, what do you mean by "saving the last coordinates in a separate variable"? If you stored each click's coordinate in the list, simply take its last item (don't forget to check for empty list):
list.get(list.size()-1);
