How do I change the below project, so that it has the following text as the 4 items of the combobox: Apples, Cars, Shrimp, Moon.

package colorcomboboxeditor;

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Component;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.ComboBoxEditor;
import javax.swing.JButton;
import javax.swing.JColorChooser;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.event.EventListenerList;

class ColorComboBoxEditor implements ComboBoxEditor
{
    final protected JButton editor;
    protected EventListenerList listenerList = new EventListenerList();

    public ColorComboBoxEditor(Color initialColor)
    {
        editor = new JButton("");
        editor.setBackground(initialColor);
        
        ActionListener actionListener = new ActionListener()
        {
            public void actionPerformed(ActionEvent e)
            {
                Color currentBackground = editor.getBackground();
                Color color = JColorChooser.showDialog(editor, "Color Chooser", currentBackground);
                
                if ( (color != null) && (currentBackground != color) )
                {
                    editor.setBackground(color);
                    fireActionEvent(color);
                }
            }
        };
        
        editor.addActionListener(actionListener);
    }

    public void addActionListener(ActionListener l)
    {
        listenerList.add(ActionListener.class, l);
    }

    public Component getEditorComponent()
    {
        return editor;
    }

    public Object getItem()
    {
        return editor.getBackground();
    }

    public void removeActionListener(ActionListener l)
    {
        listenerList.remove(ActionListener.class, l);
    }

    public void selectAll()
    {
        // Ignore
    }

    public void setItem(Object newValue)
    {
        if ( newValue instanceof Color )
        {
            Color color = (Color) newValue;
            editor.setBackground(color);
        }
        else
        {
            try
            {
                Color color = Color.decode(newValue.toString());
                editor.setBackground(color);
            }
            catch (NumberFormatException e)
            {
            }
        }
    }

    protected void fireActionEvent(Color color)
    {
        Object listeners[] = listenerList.getListenerList();
        
        for (int i = listeners.length - 2; i >= 0; i -= 2)
        {
            if ( listeners[i] == ActionListener.class )
            {
                ActionEvent actionEvent = new ActionEvent(editor, ActionEvent.ACTION_PERFORMED, color.toString());
                ((ActionListener) listeners[i + 1]).actionPerformed(actionEvent);
            }
        }
    }
}
