public class ResObj {
    public ResObj() {

    public static Image createImage(String url) {
        Image image = null;
        try {
            image = Image.createImage(url);
        } catch (IOException e) {
            e.printStackTrace();
        }

        return image;
    }

    public static int createRandom(int scale) {
        Random rand = new Random();
        int returnValue = (rand.nextInt() << 1 >>> 1) % scale;

        rand = null;
        return returnValue;
