I have been doing this for several days and I cant seem to understand how to find the total number of pixels. Also I need to find the center of the image as well which is just the average of the coordinates but everytime I put something in it doesn't work out. here is code so far:

import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.*;
import java.net.*;
public class Quiz {
static int width,height;
public static void main( String[] args ){
try {
BufferedImage image = null;
URL url=new URL("http://imc.kean.edu/cps2231/program6.png");
image = ImageIO.read(url);
height=image.getHeight();
width=image.getWidth();
System.out.println("width:"+width+ " height:"+height);

int [][] img=new int[height][width];

for (int y=0;y<height;y++)>
for (int x=0;x<width;x++)>
img[y][x]= image.getData().getSample(x, y, 0);

printImg(img);

int color=2;
int cX=0;
int cY=0;
int pixels=0;
for (int y=0;y<height;y++)> for (int x=0;x<width;x++){>
if (img[y][x] ==0){
label(img, x, y, color);
System.out.println("Color: " + color + " Object size: " + pixels + " pixels," + " Center at "+"("+cX+","+cY+")");
color++;

}
}
}

System.out.println("Total number of black objects:"+ (color-2));
printImg(img);
} catch (IOException e) { e.printStackTrace(); }
}



static void label(int[][] A, int x, int y, int color) {
if ((x>=0) && (y>=0) && (x<width)> System.out.printf("(%d,%d) color:%d\n",x,y,color);
A[y][x]=color;
label(A, x, y-1, color);
label(A, x-1,y, color);
label(A, x, y+1, color);
label(A, x+1, y, color);
}
}

static void printImg(int[][] A) {
for (int y=0;y<height;y++)> for (int x=0;x<width;x++)>
System.out.printf("%d",A[y][x]);
System.out.println();
