hi~ i am really new to processing, and i really need some help.

i want to place 50 ellipses on a board, and i want them to be placed at random.

so, i've come out with this code, but it sadly it doesn't work.

any help will be appreciated very much. thanx!

int numCircles = 50;

Circle[] circles = new Circle[numCircles]; // define the array

void setup() {

size(800,800);

  smooth();

  noStroke();
}

void draw() {
  for (int i=0; i<numCircles; i++) {

    circles[i] = new Circle(random(width),random(height-200), 30, 30); // fill the array with circles at random positions

  }

}
