Can't get JList to show in Panel

Well, I'm trying to get my final project finished for my Programming 1 course, but I seem to be having trouble getting my JList to show up in its panel. The panel itself shows, but the JList doesn't. Any help would be greatly appreciated. Code is below...

PizzaListPanel


package finalproject;


import javax.swing.*;


/**

   This class demonstrates the List Component.

*/


public class PizzaListPanel extends JPanel

{

   private JPanel pizzaPanel;         // To hold components

   private JList pizzaList;           // The pizzas

   private JScrollPane scrollPane;    // A scroll pane


   // The following array holds the values that will

   // be displayed in the pizzaList component.

   private String[] pizzas = { "Create Your Own", "King Arthur Supreme",

            "Wombo Combo", "Maui Zaui", "Chicken Garlic Gourmet", "Guinivere's Garden Delight", "Gourmet Veggie",

            "Montague's All-Meat Marvel", "Ulti-Meat", "Italian Garlic Supreme", "Smokehouse Combo",

            "Chicken Smokehouse Combo", "BBQ Chicken", "Hawaiian" };

   //Constructor

   public PizzaListPanel()

   {


      // Create a panel to hold the list.

      pizzaPanel = new JPanel();


      // Create the list.

      pizzaList = new JList(pizzas);


      // Set the selection mode to single selection.

      pizzaList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);


      // Set the number of visible rows to 12.

      pizzaList.setVisibleRowCount(12);


      // Add the list to a scroll pane.

      scrollPane = new JScrollPane(pizzaList);


      // Add the scroll pane to the panel.

      pizzaPanel.add(scrollPane);


      // Add a border around the panel.

      setBorder(BorderFactory.createTitledBorder("Pizza"));

   }

}
