Use a scale value of "-1" to reflect about an axis.

    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2 = (Graphics2D)g;
        g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                            RenderingHints.VALUE_ANTIALIAS_ON);
        int w = getWidth();
        int h = getHeight();
        Arc2D.Double arc =
            new Arc2D.Double(0, h/6, w/3, h*2/3, 45, -85, Arc2D.OPEN);
        g2.setPaint(Color.blue);
        g2.draw(arc);
        AffineTransform at = AffineTransform.getTranslateInstance(w,0);
        at.scale(-1, 1);
        g2.setPaint(Color.red);
        g2.draw(at.createTransformedShape(arc));
    }
