This is part of a code that I have for Processing. I want to center the crescent and put it in the middle I'm not sure how to do that.

void setup fullScreen void drawO // black background fill (255,255,255); ellipse (300, 300, 300, 300); fill (0,9); rect (0,0,width,height); fiu (255) ; noStroke ellipse (random (width) ,random(height),3,3); ellipseMode (RADIUS); fill (0); ellipse (220, 280, 255, 240); void setup fullScreen void drawO // black background fill (255,255,255); ellipse (300, 300, 300, 300); fill (0,9); rect (0,0,width,height); fiu (255) ; noStroke ellipse (random (width) ,random(height),3,3); ellipseMode (RADIUS); fill (0); ellipse (220, 280, 255, 240)
