at the moment I am just doing some practise in java:

Main:

```
import java.util.ArrayList;
import java.util.Random;
import javax.swing.JOptionPane;
import settelersofcatan.playerinformation;

public class settlersofcatanhelper 
{
     private ArrayList<playerinformation> PlayerArray = new ArrayList<playerinformation>();
     public static void main(String[] args) 
     {
         String NumberOfPlayersString = JOptionPane.showInputDialog("How many player");
         int NumberOfPlayers = Integer.parseInt(NumberOfPlayersString);

         for (int Counter = 0; Counter < NumberOfPlayers; Counter++)
         {
             String Name = JOptionPane.showInputDialog("Name of player " + Counter);
             String Colour = JOptionPane.showInputDialog("which colour are you playing with");
             playerinformation PlayerDetails = new playerinformation(Name, Colour, Counter);
             addplayer(PlayerDetails);
         }

     }

    public void addplayer(playerinformation player)
    {
    this.PlayerArray.add(player);
    }
}

```

Helper Class:

```
package settelersofcatan;

public class playerinformation {
    String PlayerName;
    String Colour;
    int Position;

    public playerinformation(String name, String colour, int position) 
    {
        setPlayerName(name);
        setColour(colour);
        setPosition(position);

    }

    public String getPlayerName() {
        return PlayerName;
    }
    public void setPlayerName(String playerName) {
        PlayerName = playerName;
    }
    public String getColour() {
        return Colour;
    }
    public void setColour(String colour) {
        Colour = colour;
    }
    public int getPosition() {
        return Position;
    }
    public void setPosition(int position) {
        Position = position;
    }
}

```

The Problem that I am having now is that I am trying to add a player's information and get the response "Cannot make a static reference to the non-static method addplayer(playerinformation) from the type settlersofcatanhelper".
I have looked over the code where I have this working but cant see any difference or reason why it wouldnt work. Can anyone help me?
