Adding Tiles

I want to create an applet with like 16 square tiles in it (square). Does anyone how I would be able to do this?

Code:

---

//  <applet code="Sweet16" width="600" height="300"></applet>
import java.awt.*;
import java.awt.geom.Line2D;
import javax.swing.*;

public class Sweet16 extends JApplet {
    int SIDE = 75;
    int CELLS = 8;

    public void init() {
        setLayout(new GridLayout(1,0));
        add(getTileComponent());  // component approach
        add(new TilePanel(CELLS)); // graphic approach
    }

    private JPanel getTileComponent() {
        JPanel panel = new JPanel(new GridLayout(CELLS,0));
        Dimension size = new Dimension(SIDE, SIDE);
        for(int i = 0; i < CELLS; i++) {
            for(int j = 0; j < CELLS; j++) {
                String s = String.valueOf(i*CELLS + j+1);
                JLabel label = new JLabel(s, JLabel.CENTER);
                label.setBorder(BorderFactory.createEtchedBorder());
                label.setPreferredSize(size);
                panel.add(label);
            }
        }
        return panel;
    }
}

class TilePanel extends JPanel {
    int cells;

    public TilePanel(int cells) {
        this.cells = cells;
    }

    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2 = (Graphics2D)g;
        g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                            RenderingHints.VALUE_ANTIALIAS_ON);
        double w = getWidth();
        double h = getHeight();
        double xInc = (w-1)/cells;
        double yInc = (h-1)/cells;
        g2.setPaint(Color.blue);
        for(int i = 0; i <=cells; i++) {
            double x = i*xInc;
            g2.draw(new Line2D.Double(x, 0, x, h));
        }
        for(int i = 0; i <= cells; i++) {
            double y = i*yInc;
            g2.draw(new Line2D.Double(0, y, w, y));
        }
        for(int i = 0; i < cells; i++) {
            float y = (float)(i*yInc + yInc*2/3);
            for(int j = 0; j < cells; j++) {
                String s = String.valueOf(i*cells + j+1);
                float x = (float)(j*xInc + xInc/3);
                g2.drawString(s, x, y);
            }
        }
    }
}
