ArrayIndexOutOfBoundsException

Hello coders

I am doing a matador game as a school project. Im am getting a pesky ArrayIndexOutOfBoundsException.




PlayerDB class

package fields;

import java.util.ArrayList;
import java.util.List;
import matador_BusinessLogic.Player;

public class PlayerDB {
	public int numberOfPlayers;
	
	public Player[] allPlayers = new Player[numberOfPlayers];
	public List<Player> playersInGame = new ArrayList<Player>();
	
	public PlayerDB(int numberOfPlayers){
		this.numberOfPlayers = numberOfPlayers;
	}
	
	public void createAndAddPlayers(String[] name, int[] carColor){
		for (int i=0; i<numberOfPlayers; i++){
			allPlayers[i] = new Player(name[i], carColor[i], i);
			playersInGame.add(allPlayers[i]);
		}
	}
	
	public  Player nextPlayerInGame(Player currentPlayer) {
		int index = playersInGame.indexOf(currentPlayer);
		if (++index == playersInGame.size())
			index = 0;
		return playersInGame.get(index);
	}

}

GameController class

package matador_BusinessLogic;
import fields.*;

public class GameController {
	public static String[] allColors = new String[] 
			{ "Blå", "Grøn", "Rød","Gul", "Hvid", "Sort" };
	public static MatadorRaflebaeger diceCup = new MatadorRaflebaeger(2, 6);
	public static MatadorFieldList board = new MatadorFieldList();
	public static GameBoundary gb = new GameBoundary();
	private PlayerDB db;
	private static Field currentField;
	private static Player currentPlayer;

	public void startGame() {
  final int STOP = 30000;
		// Spørger efter antallet af spillere og gemmer værdien i PlayerDB
		int numberOfPlayers = gb.askForPlayerCount();
		// creates PlayerDB object and sets numberOfPlayers 
		db = new PlayerDB(numberOfPlayers);

Sry accidently posted. Here is the rest of the relevant code from GameController

tring[] names = new String[db.numberOfPlayers];
		int[] alreadyPickedColors = new int[db.numberOfPlayers];
		
		for (int i = 0; i < db.numberOfPlayers; i++) {
			names[i] = gb.getName(i + 1);
			alreadyPickedColors[i] = gb.askForColor(allColors,alreadyPickedColors, i);
		}
		
		db.createAndAddPlayers(names, alreadyPickedColors);
		
		for (int i = 0; i < db.numberOfPlayers; i++) {
			gb.GuiAddPlayer(db.allPlayers[i].getName(), db.allPlayers[i].getMoney(), db.allPlayers[i].getCarColor());
		}
		
		currentPlayer = db.playersInGame.get(0);

The line that causes the exception is line 12 in 3rd code snippet.

Looking forward to some feedback.
