[picia2222]

Hello. I have analog clock app and want to change hands color using setter and getter. I write some code but not work. Can You help me?
My code:

        private Color tloKolor;
	BufferedImage clockFace ;
	
        //konstruktor bezparametrowy public ClockComponent(){};
        public ClockComponent(){};
	
      public void setKolor (Color R) {tloKolor=R;}
      public Color getKolor () {return tloKolor;}

                //włączenie antialiasingu aby grafika ładniej wyglądała
		graphics.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);

		if (clockFace==null) {
                        //wczytanie obrazka z tarczą
