how can I draw a board in 2d array?

[java_fun2007]

hi
i'm trying to create a game called "Gomuku", but I don't know how to start this is my first game ever.. I need to create 10x10 board, JPanel, JButton to start the game "New Game" and a class called Square.java that holds int x,y,accupied;

this is Square.java class

Code:

public class Square {
    private final int row ;
    private final int col ;
    private int accupied=0;


    public Square(int r, int c) {
      row = r;
      col = c;
        
    }

   public void setAccupied(int ac) {
		accupied = ac;
   }
   
public int getAccupied()
  {
  	return accupied;
  }
  
        }//end square class

Code:

class Board extends JPanel
{
	private Square sq[][] ;
	 
	public void paintComponent(Graphics g)
	{  sq[10][10] = new Square(10,10);
		 for (int row = 0;  row < 10;  row++) {
             for (int column = 0;  column < 10;  column++) {
                Square[row][column] = 0;
             }
          }
g.drawRect();
	}
}//end class board

I want to draw the squares now with this method g.drawRect(); but it takes four parameters do you know where to get examples like that maybe I will get benefit of them?
I'm just beginning to learn how to create games like these using Square.java class and a JPanel.

Thanks

you would need to use a thread if you wanted it to update constantly. I would recommend using images and just using a Gridlayout. Then just updating the images everytime someone makes a move. your way works, but it over complicates the problem. Also if you us buttons or images you can just add a mouse listener to it.

Code:

import java.awt.*;
import java.awt.geom.Line2D;
import javax.swing.*;

public class MakingAGrid extends JPanel {
    SquareRx[][] squares;
    final int PAD = 20;

    public MakingAGrid() {
        int ROWS = 10;
        int COLS = 10;
        squares = new SquareRx[ROWS][COLS];
        for(int i = 0; i < ROWS; i++) {
            for(int j = 0; j < COLS; j++) {
                squares[i][j] = new SquareRx(i, j);
            }
        }
    }

    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2 = (Graphics2D)g;
        g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                            RenderingHints.VALUE_ANTIALIAS_ON);
        int w = getWidth();
        int h = getHeight();
        double xInc = (double)(w - 2*PAD)/squares[0].length;
        double yInc = (double)(h - 2*PAD)/squares.length;
        // Draw vertical grid lines.
        g2.setPaint(Color.blue);
        for(int i = 0; i <= squares[0].length; i++) {
            double x = PAD + i*xInc;
            g2.draw(new Line2D.Double(x, PAD, x, h-PAD));
        }
        // Draw horizontal grid lines.
        for(int i = 0; i <= squares.length; i++) {
            double y = PAD + i*yInc;
            g2.draw(new Line2D.Double(PAD, y, w-PAD, y));
        }
    }

    public static void main(String[] args) {
        MakingAGrid test = new MakingAGrid();
        JFrame f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.add(test);
        f.setSize(400,400);
        f.setLocation(200,200);
        f.setVisible(true);
    }
}

class SquareRx {
    private final int row;
    private final int col;
    private boolean occupied = false;

    public SquareRx(int r, int c) {
        row = r;
        col = c;
    }

    public void setOccupied(boolean occupied) {
        this.occupied = occupied;
    }

    public boolean isOccupied() {
        return occupied;
    }
}
