ChoiceList within a Frame problem

Question

Hi,
I have to create a GUI using swing and I don't know how to put a ChoiceList(ComboBox) into a panel.
This is what I wrote and that is the error message after compilation.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class ChoiceDeparture2 extends Frame
implements ItemListener{
     Choice os;
     ChoiceDeparture2(){
     os = new Choice();
     Panel panel = new Panel();
     panel.setLayout(new GridLayout(1,2,20,0));
     panel.add(new Label("Departure City"));
          os.add("Any");
          os.add("SFO");
          os.add("LAX");
          os.add("DAL");
          os.add("FRA");
          os.add("BOM");
          os.add("DEN");
          os.add("ABQ");
          os.add("ATL");
          panel.add(os);
          os.addItemListener(this);
     add(panel, BorderLayout.CENTER);
public void itemStateChange(ItemEvent ae){
     repaint();
public static void main(String[] args){
     ChoiceDeparture2 ChoiceD = new ChoiceDeparture2();
     ChoiceD.setVisible(true);
     } //end main
}//end ChoiceDeparture
-error message-----------------------------------------------------------------------------
A:\Java\ChoiceDeparture2.java:5: ChoiceDeparture2 should be declared abstract; it does not define itemStateChanged(java.awt.event.ItemEvent) in ChoiceDeparture2
public class ChoiceDeparture2 extends Frame

Answer 1

you need to check your spelling
public void itemStateChanged(ItemEvent e){}
