how to show pixel array of an image in python or java??? help me

Are you trying to get a 2D array if each pixel color? In the Java BufferedImage class, there is the method:

getRGB(int x, int y)

Therefore, you could just loop through each pixel and add it to your array, like this:

int[][] array = new int[img.getWidth()][img.getHeight()];
for (int i = 0; i < img.getWidth(); i++) {
   for (int j = 0; i < img.getHeight(); j++) {
      array[i][j] = img.getRGB(i, j);
   }
}

This will give you a 2D array of the RGB value of each pixel.

You might study this Java example that uses the graphics context's drawImage() to enlarge an image and report the color of each pixel.

You might want to look in to the Python Image Library (PIL), I recommend it.
