Generating a circle.

Game Mechanics
#1

So say I have an array of tiles:

Tile[] tiles = new Tile[100 * 100];

How would I generated a filled circle in that array?
I found some code in wiki, but it seems really complex and I can’t really understand it. It is called Midpoint circle algorithm. Does anyone have a good working circle generation algorithm?
