Here a sample:

=================================
import java.applet.Applet;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JComboBox;
import javax.swing.JOptionPane;

public class ComboBoxApplet extends Applet {
    private JComboBox fComboBox;
    public void init() {
        // create Combobox
        fComboBox = new JComboBox();
        // add items
        fComboBox.addItem("Item 1");
        fComboBox.addItem("Item 2");
        fComboBox.addItem("Item 3");
        fComboBox.addItem("Item 4");
        fComboBox.addItem("Item 5");
        fComboBox.addItem("Item 6");
        fComboBox.addItem("Item 7");
        fComboBox.addItem("Item 8");
        fComboBox.addItem("Item 9");
        fComboBox.addItem("Item 10");
        fComboBox.addItem("Item 11");

        // make the combobox "large" so all items are displayed without
        // scrolling
        fComboBox.setMaximumRowCount(15);

        // add a listener to handle the selection
        fComboBox.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                onComboboxSelected();
            }
        });

        // add the combobox to the applet
        add(fComboBox);
    }

    protected void onComboboxSelected() {
        // Refer to the currently selected item either by index (<0 when nothing
        // is selected) ...
        int index = fComboBox.getSelectedIndex();
        // or by the item (may be null) ...
        Object selection = fComboBox.getSelectedItem();

        // Do anything you want when an item is selected.
        // (e.g. display a dialog)
        JOptionPane.showMessageDialog(null, "Selected " + index + "\n("
                + selection + ")");
    }
}
