I'm attempting to fill individual pixels of an image in a checkerboard pattern.
No matter what I do, it fails to work. My logic is wrong somewhere.
Anyone willing to take a look?

        public void checkerFilter() {

        int r = 0;
        int g = 102;
        int b = 0;
        int x = 0, y = 0;
        int col = (r << 16) | (g << 8) | b;

        for (int i = 0; i < img.getHeight(); i++) {
            for (int j = 0; j < img.getWidth(); j++) {

                if (x == img.getWidth()) {
                    x = 1;
                    break;
                } else if (x == img.getWidth() - 1) {
                    x = 0;
                } else {
                    img.setRGB(x, y, col);
                    x += 2;
                }
            }

            y++
            img.setRGB(x, y, col);

        }

        displayImage(); //displays image in jframe

    }
