Integer.toHexString() returns a string. You can't perform the mathematical AND operation on a string! What are you trying to do, actually? If you want readable hex of just the one color channel: return Integer.toHexString(rgb & 0xFF00FFFF);

| Actually, i want to edit each pixel's RGB value. So something like, i took one pixel in some coordinate, i get the RGB value of it, and then increase/decrease the value of green for example(ex. found green's value = a3, increase it to max = ff or dd, (i use JSlider for each RGB, and alpha too). And then return it to appropriate method for image filtering. Sore de. ^^ |

You will want to use the class PixelGrabber.
