MouseRelased with an if Statement

I'm learning MouseListener. Now I have a Problem. I want it between my two JMenuItems selects and then open I've created with NetBeans GUI Panel. My JMenuItems are Blueberry and Cherry.

MouseListener ml = new MouseListener() {         

        public void mouseReleased(MouseEvent e) {
            ((JMenu) e.getSource()).doClick();
            if ();
        }
    };
    Blueberry.addMouseListener(ml);
    Cherry.addMouseListener(ml);
