Need to draw 0 in a for loop, but it keeps getting skipped

Question

I'm trying to make a drawing panel that draws little circles with numbers in it, going from 0 to 9. However, the for loop, for one reason or another, keeps skipping 0. I've tried setting i to -1, but that doesn't change anything. Conversely when I set the condition to i < 11, it draws all numbers from 1 to 10.

Here's the code so far:

`

// Draws boxed ovals using a while loop.
import java.awt.*;

public class DrawLoop 
{
    public static void main(String[] args) 
    {
        DrawingPanel panel = new DrawingPanel(502, 252);
        panel.setBackground(Color.CYAN);
        Graphics g = panel.getGraphics();
        
        String iValue = "";
        int sizeX = 50;  // size of boxes
        int sizeY = 25;
        int i;
        for (i = 0; i < 10; i++) { // start at i = 0 
            int cornerX = i*50;  // calculate upper left corner
            int cornerY = i*25;
            g.setColor(Color.WHITE);
            g.fillOval(cornerX + 5, cornerY + 5, sizeX-10, sizeY-10);
            g.setColor(Color.BLACK);
            g.drawRect(cornerX, cornerY, sizeX, sizeY);
            iValue = "" + i;
            g.drawString(iValue, cornerX - 29, cornerY - 8);
        }
    }
}
