Grid of circles

Hi, I'm trying to make a square grid of circles (ex: 3x3, 5x5) using a for loop.

for(int i=1; i<=Lines; i++){
g.setColor (Color.RED);
g.fillOval(x+(SIZE*i/(Lines+1)),y+(SIZE/(Lines+1)),4,4);
}

This loop creates only a single row of circles. I'm at a loss as to how to modify this to create an entire grid of circles.
Any help is appreciated, thanks

You can use two loops, one inside the other.
If you still want to use only one:

For a grid of n x m fields (n rows, m columns), you'll have to draw n*m circles, so
int count = n*m;

You would loop from i=0 to i<count.
If (x1, y1) are the coordinates of each circle, and (x,y) is the starting point, then:

row = i / n (integer division)

and

column = i &#37; m.


So,

x1 = x + SIZE * column;
y1 = y + SIZE * row; // if you are drawing bottoms-up, then y1 = y - SIZE * row.

Unless there is a compelling reason to do otherwise go with TheGreatCthulhu's first suggestion of 2 loops. It's easier to write, easier for someone else (or yourself after 'n' years) to read and understand and less prone to errors.

Code:

---

for(int x = 0; x < nCols; x++) {
    for(int y = 0; y < nRows; y++) {
        ... your code here...
    }
}

Thank you both very much!
