Question

So far I have the following code that reads a 30×40 pixel .bmp file:

public void setUp() throws IOException
{
    BufferedImage image =
        ImageIO.read(getClass().getResource("circle1.bmp"));
    greenInputData = new byte[30][40];

    for (int x = 0; x < greenInputData.length; x++)
    {
        for (int y = 0; y < greenInputData[x].length; y++)
        {
            int color = image.getRGB(x, y);
            greenInputData[x][y] = (byte)(color >> 8);
        }
    }
    System.out.println(greenInputData);
}

The console gives me the following right now when I call System.out.println(greenInputData):

[[B@1c8a1c9d
[[B@1cb4ee66
[[B@262580b3
[[B@450a3962
[[B@5d7138f4
[[B@44443799

[[B@3849ca75
[[B@ebe5687
[[B@671ef55c
[[B@68c6fc84
[[B@53dc5341

But I want to be able to see an array printout of the image I am reading. For example, if I reading a bitmap of a circle, I want to be able to System.out.println() out a 30×40 bitmap array like the following:

<---------30---------------->
000000000000000000000000000000 ^
000000111110000000000000000000 |
000001111111100000000000000000 |
000011111111110000000000000000 |
000011111111110000000000000000 40
000001111111100000000000000000 |
000000011110000000000000000000 |
000000000000000000000000000000 |

Hint :

You are forming greenInputData right

Problem is with the way you are displaying it.

hint: it is a 2d array
