求反编译后的一段代码解析

DJ Java Decompiler反编译代码为：
 public Engine onLoadEngine()
    {
        Resources resources = getResources();
        Constants.CAMERA_HEIGHT = resources.getDisplayMetrics().heightPixels;
        Constants.CAMERA_WIDTH = resources.getDisplayMetrics().widthPixels;

        Saver.setSharedPreferences(getSharedPreferences(Saver.PREF_NAME, 0));
        Saver.loadLastLevel();
        Constants.STAGE_SCALE_Y = Constants.CAMERA_HEIGHT / Constants.STAGE_HEIGHT;
        Constants.STAGE_SCALE_X = Constants.CAMERA_WIDTH / Constants.STAGE_WIDTH;
_L6:
        if(Constants.tasks.size() != 0) goto _L2; else goto _L1
_L1:
        String as[];
        as = getImage();
        ShuffleArray.shuffleString(as);
        int i = 0;

jd-gui反编译代码为：

麻烦写出正确的代码，谢谢！
