pixel scanning too slow

I am making a program that scans randomly for pixels on the screen. It uses the robot class to check (robot.getPixelColor(x,y)) each pixel it randomly hops to. The problem is: It is TOO SLOW. I heard you can use BufferedImages, Rasters,etc. Can someone point me to the right direction? Thanks!

Nevermind. I solved it. I had to use Raster to get a int[] array.

I've seen this question posted before, can you post the code that gets the int[] array?

Code:

---

        Rectangle screenRect = new Rectangle(0, 0, Toolkit.getDefaultToolkit()
                                .getScreenSize().width, Toolkit.getDefaultToolkit()
                                .getScreenSize().height);
                BufferedImage grid = robot.createScreenCapture(screenRect);
                int X = random(0, Toolkit.getDefaultToolkit().getScreenSize().width);
                int Y = random(0, Toolkit.getDefaultToolkit().getScreenSize().height);
                int tst[] = null;
                Raster k;
                k = grid.getData();
                tst = k.getPixel(X, Y, tst); //X = the x pixel, Y = the y pixel

The value 'R' is tst[0], G is tst[1] and B is tst[2]

Thanks for the code.
