checkerboard help

[armedrabbit]

Hi i am very new to java still and i cannot figure out what is wrong with this java program.

I will need 3 classes: Checkerboard, CheckerboardComponent, and CheckerBoardViewer.

[code]import java.awt.Graphics2D;
import java.awt.Rectangle;

/**
This class displays a checkerboard with squares,
alternating between white and black.
*/
public class CheckerBoard
{
/**
Creates a CheckerBoard object with a given number of squares.
@param aNumSquares the number of squares in each row
@param aSize the size of each square
*/
public CheckerBoard(int aNumSquares, int aSize)
{
numSquares = aNumSquares;
size = aSize;
}

/**
Method used to draw the checkerboard.
@param g2 the graphics content
*/
public void draw(Graphics2D g2)
{
//
}

private int numSquares;
private int size;
}

CheckerBoardComponent.java

import javax.swing.JComponent;
import java.awt.Graphics;
import java.awt.Graphics2D;

public class CheckerBoardComponent extends JComponent
{
public void paintComponent(Graphics g)
{
Graphics2D g2 = (Graphics2D) g;

final int NSQUARES = 8;

int size = Math.min(getWidth(), getHeight()) / NSQUARES;
CheckerBoard cb = new CheckerBoard(NSQUARES, size);

cb.draw(g2);
}
}

CheckerBoardViewer.java

import javax.swing.JFrame;

/**
This program displays a checkerboard.
*/
public class CheckerBoardViewer
{
public static void main(String[] args)
{
JFrame frame = new JFrame();

final int FRAME_WIDTH = 330;
final int FRAME_HEIGHT = 360;

frame.setSize(FRAME_WIDTH, FRAME_HEIGHT);
frame.setTitle("CheckerBoardViewer");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOS E);

CheckerBoardComponent component = new CheckerBoardComponent();
frame.add(component);

frame.setVisible(true);
}
}[code]
