Programming my first simple java game

Question

I want to program a Java Applet called: a knight's tour.
The game goes as follows:
When you start the applet a chessboard will be shown.
When you click on a compartment the knight will appear. Then you've got to click on the next compartment. The applet has to check if this is a "knight move" and if the square has'nt been visited yet.
You win when you have visited all the compartiments.
Can anywone help me? The chessboard isn't a problem. But for example, when you click on a point, how can I ask the color of that specific location?
Thanks for the reaction.

I very much agree with yawmark. I'm also not really sure how far you want to take this in terms of being an actual chess game, since - to my mind at least - your post is not too clear. Since you mentioned that you did not really understand Java very well, I again 2nd what yawmark said. Still, since you were considerate and frank, I had a few minutes and so coded up what I meant in my prior post. As I said, I'm sure there are better approaches, but since I'm not really sure where you're headed with this, I thought I'd post the code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class ChessGame  extends JFrame {
  private boolean isRed;
  private JLabel  jl;
  public ChessGame() {
    super( "ChessGame" );
    Container c = this.getContentPane();
    JPanel jp = new JPanel();
    jp.setLayout( new GridLayout( 8, 8, 0, 0 ) );
    for ( int idx = 1; idx < 65; idx++ ) {
      jp.add( buildJButton() );
      if ( idx % 8 == 0 ) isRed = !isRed;
    c.add( jp );
    jl = new JLabel( "click on a square" );
    c.add( jl, BorderLayout.SOUTH );
    setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
    setBounds( 100, 100, 500, 500 );
    setVisible( true );
  public JButton buildJButton() {
    final JButton jb = new JButton( "" );
    jb.setBorderPainted( false );
    if ( isRed ) jb.setBackground( Color.red );
    else         jb.setBackground( Color.black );
    isRed = !isRed;
    jb.addActionListener( new ActionListener() {
      public void actionPerformed( ActionEvent ae ) {
        if ( ( ""+jb.getBackground() ).startsWith( "java.awt.Color[r=0" ) )
          jl.setText( "black" );
        else
          jl.setText( "red" );
    return( jb );
  public static void main( String[] argv ) {
    new ChessGame();
}HTH
