 // Create a list

    String[] items = {"A", "B", "C", "D"};

    JList list = new JList(items);

    // Add a listener for mouse clicks

    list.addMouseListener(new MouseAdapter() {

        public void mouseClicked(MouseEvent evt) {

            JList list = (JList)evt.getSource();

            if (evt.getClickCount() == 2) {          // Double-click

                // Get item index

                int index = list.locationToIndex(evt.getPoint());

            } else if (evt.getClickCount() == 3) {   // Triple-click

                // Get item index

                int index = list.locationToIndex(evt.getPoint());

                // Note that this list will receive a double-click event before this triple-click event

            }
