String array error using JFrame

I'm creating a simple roulette remake. I'm using JFrame. Everything about my code works fine, except for one thing. I marked it in my code, it's the method ButtonAction. I'm sorry I might be posting a lot of code, but that method is probably the only method you should be looking. I'm just posting the rest of the code below for extra information. Anyway, under that method I made a string array to name each button differently. At first I made it like this:

  public ButtonAction(int i) {

      String name = "Button " + i;
      putValue(NAME, name);
      this.value = i;
  }

Like this each button was called Button 1, Button 2 etc. That was no problem at all, but I wanted each button to have a completely different name, so I made this, a string array:

public ButtonAction(int i) {

        String[] ButtonNaam = {"Chances Simples", "Douzaines", "Colonne", "Transversale simple", "Carré", "Transversale pleine", "Cheval", "Plein"};
        String name1 = ButtonNaam[i];

        putValue(NAME, name1);
        this.value = i;

And then I got the error, unfortunately. What exactly am I doing wrong?

This is the full code if it helps:

import java.awt.CardLayout;
import java.awt.Component;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.GridLayout;
import java.awt.Toolkit;
import java.awt.event.ActionEvent;

import javax.swing.*;

public class RouletteGUI extends JPanel {
   // preferred size dimensions
   private static final int PREF_W = 450;
   private static final int PREF_H = 300;

   // number of buttons displayed
   private static final int BUTTON_COUNT = 8;
   public static final String BLANK_PANEL = "blank";
   public static final String MAIN_PANEL = "main panel";
   private CardLayout cardLayout = new CardLayout();



   public RouletteGUI() {
      // create JPanel to hold our buttons. use a grid layout with 1 column
      JPanel buttonPanel = new JPanel(new GridLayout(0, 1, 5, 5));
      for (int i = 1; i <= BUTTON_COUNT; i++) {
          // create a new JButton and give it a an Action
         JButton button = new JButton(new ButtonAction(i));
         // add it to the buttonPanel
         buttonPanel.add(button); 
      } 
      // main JPanel to hold the buttonPanel
      JPanel mainPanel = new JPanel(new FlowLayout(FlowLayout.LEADING));
      mainPanel.add(buttonPanel);

      // set this class's layout
      setLayout(cardLayout);
      add(mainPanel, MAIN_PANEL); // add mainPanel
      add(new JPanel(), BLANK_PANEL);  // add a blank JPanel
   }

   @Override // so JPanel will be at least our desired size
   public Dimension getPreferredSize() {
      Dimension superSz = super.getPreferredSize();
      if (isPreferredSizeSet()) {
         return superSz;
      }
      int prefW = Math.max(superSz.width, PREF_W);
      int prefH = Math.max(superSz.height, PREF_H);
      return new Dimension(prefW, prefH);
   }

   // our AbstractAction class, an ActionListener "on steroids"
   private class ButtonAction extends AbstractAction {
      private int value;

      public ButtonAction(int i) {

            String[] ButtonNaam = {"Chances Simples", "Douzaines", "Colonne", "Transversale simple", "Carré", "Transversale pleine", "Cheval", "Plein"};
            String name1 = ButtonNaam[i];

            putValue(NAME, name1);
            this.value = i;
            //HERE I GET THE ERROR
            //!!!!!!!!!!!!!!!!!!!
      }

      @Override
      public void actionPerformed(ActionEvent e) {
         // TODO: do some number specific action based on value
         // For a trivial example:
         String message = "Button pressed: " + value;
         JOptionPane.showMessageDialog(null, message);

         // swap view to a blank view
         cardLayout.show(RouletteGUI.this, BLANK_PANEL);
      }
   }

   // create and display GUI in a thread-safe manner
   private static void createAndShowGui() {

      RouletteGUI mainPanel = new RouletteGUI();

      JFrame frame = new JFrame("Roulette");
      frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
      frame.getContentPane().add(mainPanel);
      frame.pack();
      frame.setLocationByPlatform(true);
      frame.setVisible(true);
      frame.setResizable(false);
      Dimension dimension = Toolkit.getDefaultToolkit().getScreenSize();
      int x = (int) ((dimension.getWidth() - frame.getWidth()) / 2);
      int y = (int) ((dimension.getHeight() - frame.getHeight()) / 2);
      frame.setLocation(x, y);
   }

   public static void main(String[] args) {
      SwingUtilities.invokeLater(new Runnable() {
         public void run() {
            createAndShowGui();
         }
      });
   }


}

And this is the error code I get:
