Processing is a java-like scripting language that is simple but yet powerful that can be used to do computer animations and graphics (images). Some simple examples of using Processing can be found at link: https://helloacm.com/processing/. Today, here is another simple example that uses this scripting language to draw a chess board. We put noLoop to disable animations (draw over and over again), thus it is straightforward to paint in the draw() function.

final int WIDTH = 500;
final int HEIGHT = 500;
final int BLOCKX = WIDTH / 8;
final int BLOCKY = HEIGHT / 8;
void setup() {
size(WIDTH, HEIGHT);
noLoop();
}
void draw() {
for (int i = 0; i < 8; i ++) {
for (int j = 0; j < 8; j ++) {
if ((i + j + 1) % 2 == 0) {
fill(255, 255, 255); // white
} else {
fill(0, 0, 0); // black
}
rect(i * BLOCKX, j * BLOCKY, (i + 1) * BLOCKX, (j + 1) * BLOCKY);
}
}
}
Previously, we have shown different programming languages [1][2][3][4] to do such similar things… painting a chess board is one of the interesting beginner’s tasks.

How do I make a checker board only using turtle graphics and java.awt and keyboardreader .
is’nt that a bit of a weird way to flip black rectangles to white, couldnt u just say if((i + j) % 2 == 1) instead of if((i + j + 1) % 2 == 0)?
yes, it is essentially the same thing – but from different aspects
Im sorry to ask, but I dont really understand this bit of code
