Help with Grid Layout

[coco]

Hello, I'm trying to write a game in Java. The Sea Battle game where you should hit and sink the opponents ships...
It has to be in a field 10x10 squares and i had written the code for a square.

Code:

import java.awt.*;
import javax.swing.*;

public class Tile extends JButton{
public Tile() {
super("");
}
public void paintComponent (Graphics g) {
g.setColor (getForeground());
}
}

But i have know idea what to do next. I know I should put them in a Grid Layout, but how the hell should I program the ships?
Thanks.

Here's an idea. Try drawing your grid in the paintComponent method of a JPanel, the sea, and drawing images of the ships in the grid cells. Keep a boolean array that matches the grid structure. You can set/change the boolean values for availability of targets. Use keyboard navigation to maneuver your ship among the cells, to rotate and to fire.
