How To Wait A ticker.

Question

This Is The Ticker method I got from StackOver Flow.

public void setText(String text) {
    this.text = text;
}

public String getText() {
    return text;
}

public Ticker(String text) {
    this.text = text;
    final int width = Font.getDefault().getAdvance(text);
    TimerTask timerTask = new TimerTask() {
        public void run() {
            offset--;
            if (offset + width == 0) {
                offset = screenWidth;
            }
            invalidate();
        }
    };
    timer.scheduleAtFixedRate(timerTask, delay, delay);
}

protected void layout(int width, int height) {
    int w = Display.getWidth();
    int h = Font.getDefault().getHeight();
    setExtent(w, h);

}

protected void paint(Graphics graphics) {
    graphics.drawText(text, offset, 0);
}

}
