Hot cup of Java sir?

So far we have seen single-dimension arrays. It is possible to define multi-dimensional arrays which mean that you can store tables or even 3D structures.

int image[][] = new image [5][5];

Ok the above image is crap but we can represent it in a 2d array -

image[1][0] = 1;
image[3][0] = 1;
image[0][1] = 1;
image[1][1] = 1;
image[2][1] = 1;
image[3][1] = 1;
image[3][1] = 1;
image[1][2] = 1;
image[3][2] = 1;
image[0][3] = 1;
image[1][3] = 1;
image[2][3] = 1;
image[3][3] = 1;
image[4][3] = 1;
image[1][4] = 1;
image[3][4] = 1;

The 1 represents the square being red and 0 represents the square being white. This is how bitmap images are stored. We can then encode RGB values as a int number and store it in a 2d array. This is how bitmap images are stored.
