I want to create a simple tic tac toe applet. Below is my code
Questions:
1. For my actionPerformed method. Instead of labelling every button with numbers (1~9) and using getActionCommand to identify which button is clicked, is there other simple way to detect which button has been clicked? So that i need not copy my codes in actionPerformed() 9 times..

2. How do i detect a win/lose/tie? How do i code it?

Code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

/**
 * Simple tic-tac-toe applet. Win/tie status is shown at the top of the
 * applet.
 */
public class TicTacToe extends JApplet implements ActionListener {
	JLabel messagesLabel=new JLabel("X goes first");
	JPanel displayPanel=new JPanel(new GridLayout(3,3));
	private static int count=0;
	private static JButton b1=new JButton("1");
	private static JButton b2=new JButton("2");
	private static JButton b3=new JButton("3");
	private static JButton b4=new JButton("4");
	private static JButton b5=new JButton("5");
	private static JButton b6=new JButton("6");
	private static JButton b7=new JButton("7");
	private static JButton b8=new JButton("8");
	private static JButton b9=new JButton("9");

	public void init(){
