Using main method to start off app

[garrym]

I'm stuck on how to use the main method. Before I noved the project to another computer it just kept telling me that all the methods I put couldn't run as they weren't static. How are you meant to initialize the main method.

Also now it's stopped working since I moved the project. Netbeans keeps saying I have no main class. Here's the code:

import java.util.ArrayList;
//import java.util.Iterator;
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import javax.swing.*;

public class TicTacToe extends Panel implements ActionListener {
    // the money inside a money bag
    //public static int REWARD = 1000;
    // the cost of opening an empty bag
   // p//ublic static int COST = 250;
    // the size of the game board and total number of money bags
    public static int ROW_COUNT = 3;
    public static int COLUMN_COUNT = 3;
    //public static int BAG_COUNT = 10;
    // the fields that report how a player’s doing
    //private JTextField moneyField;
    //private JTextField foundField;
    // the restart button
    public JButton restart;
    // a player’s money and the number of money bags found
    //public int money;
    //public int found;
    // the game board
    private Board board;



    public int numPlayers = 2;
    public Player currPlayer;
    ArrayList<Player> players = new ArrayList<Player>();

    //ArrayList player = new ArrayList();
    //public Player[] player;


    // create the app
public static void main(String[] args) {
	System.out.println("Hello world!");
}

There are several ways to do it.

class Foo {
    public Foo() {}

    public Foo(String s) {
        run(s);
    }

    public void run(String s) {
        System.out.println(s);
    }

    public static void main(String[] args) {
        new Foo("Hello World");
        new Foo().run("Hello World");
        Foo f = new Foo();
        f.run("Hello World");
    }
}

I've sorted the no main class problem - it was the IDE trying to open a different file/project from a previous project that was left open but I'm still stuck on how to initialize a desktop application.

Any tips please?
