Array of arrays

Hello:
I´m trying to make an object [][], just like normal humans uses in GUI...
But the way I´m working doesn´t seems to be very efficient...
The program is a futbol Manager:
I have a Player class with lots of variables (name, attack, number...)
There is also a class Team with 22 players in it.
How can I make a method in Team that gives me an Object[][] to make a JTable in GUI?????????
I will send some code "for more understanding"

/*CLASS PLAYER*/
import java.util.*;
import java.lang.*;


public class Player
{
    static Vector allPlayers;
    String name;
    int number;
   
       
    public Player (String name, int number)
    {
        this.name = name;
        this.number = number;
        Team.teamPlayers.add(this);
    }
   
    public String getName()
    {
        return name;
    }
    public int getNumber()
    {
        return number;
    }
   
    public static Object [] playerValues(Player p)
    {       
       
            Object[] playerValues = {p.getName(),new Integer(p.getNumber())};
            return playerValues;
    }
   
    public String toString()
    {
        return name+ number;
    }
   
       
       
       
   
}
/*CLASS TEAM*/
import java.util.*;

public class Team
{
   
    static Vector teamPlayers;
    String name;
   
   
   
    public Team (String name)
    {
        this.name = name;
       
    }
   



    public static Object [][] playersOnTeam(Team t)
    {
        Object [][] playersOnTeam = null;
       
        for (int x = 0; x< t.teamPlayers.size(); x++)
        {
            Player  actualPlayer = (Player)teamPlayers.elementAt(x);
           
            playersOnTeam[x] = Player.playerValues(actualPlayer);
               
        }
       
        return playersOnTeam;
       
    }
   
    public String toString()
    {
        return name;
    }
   
    public static void main (String[] args)
    {
          Player a = new Player("Daniel",1);
        Player b = new Player("Thomas",2);
        Player c = new Player("Nikolai",5);
        Player d = new Player("Andreas",7);
        Player e = new Player("Jose",3);
       
        Team t = new Team("Ruc");
       
        System.out.println(t);
       
        System.out.println(a);
       
       
        //System.out.println(Team.playersOnTeam(t));
        System.out.println(Player.playerValues(a));
   
    }
       
       
   
}
