How does Robot's getPixelColor(int x, int y) method work?

Question

How exactly does the method getPixelColor(int x,int y) from the Robot class work? I tried this code fragment:

try 
{
     Robot robos = new Robot();
}
cat

how can i solve this problem?

Don't use the Robot to get the colors pixel by pixel. Use the Robot the create a BufferedImage of the screen. Then you can use the getRGB() method of the BufferedImage to get the int value that represents the color of the pixel. You can then create a Color Object using this int or parse out the red/green/blue values directly.
