Java Programmers..?

i'm learning java at uni just now and usually i prepare my program before the practical.
normally, myself and TClite try to program at the same time, conversing on msn messenger until one of us finishes first (him without exception :angry: )
so this week, i think it only fair to cheat :rolleyes:

anyway, does anyone know how i would insert a loop into the following program so that the program would ask for another country until the user presses the "cancel" button?

a very big thanks in advance too :)

/**
* CheeseSwitch
*
*


* Choose a country using ListBox and a Switch Statement
*
* @author

import javabook.*;

public class CheeseSwitch
{
public static void main (String[] args)
{
MainWindow mainWindow = new MainWindow("Country Chooser");
MessageBox messageBox = new MessageBox( mainWindow );

ListBox countryList = new ListBox( mainWindow, "Select Country");

int choice;

mainWindow.setVisible(true);

countryList.addItem("Scotland");
countryList.addItem("England");
countryList.addItem("France");
countryList.addItem("Greece");
countryList.addItem("Netherlands");

choice = countryList.getSelectedIndex();

switch ( choice )
{

case ListBox.NO_SELECTION :
messageBox.show("No selection made");
break;

case ListBox.CANCEL:
messageBox.show("Cancelled !");
break;

case 0 :
messageBox.show("Scottish Cheese");
break;

case 1 :
messageBox.show("English Cheese");
break;

case 2 :
messageBox.show("French Cheese");
break;

case 3 :
messageBox.show("Greek Cheese");
break;

case 4 :
messageBox.show("Dutch Cheese");
}
}
}


p.s. sorry in advance for the indentation, for some reason the board software likes to mess it up :(

Here is the modified code for it. You don't need to show mainWindow, showing message box is enough as you are only using message box and listbox. So I got rid of it. If you want you can add that. Doesnt make a difference only brings an empty window in the background of your listbox.

The rest of the code is clear itself. Feel free to ask.

Code:

---

import javabook.*;

public class CheeseSwitch{
       

        public static void main (String[] args){
 
 MainWindow mainWindow = new MainWindow("Country Chooser");
 MessageBox messageBox = new MessageBox( mainWindow );

 int choice =0;

 while(choice!=ListBox.CANCEL){
         ListBox countryList = new ListBox( mainWindow, "Select Country");
         countryList.addItem("Scotland");
         countryList.addItem("England");
         countryList.addItem("France");
         countryList.addItem("Greece");
         countryList.addItem("Netherlands");

         choice = countryList.getSelectedIndex();


         switch ( choice ){

  case ListBox.NO_SELECTION :
  messageBox.show("No selection made");
  break;
        
  case 0 :
  messageBox.show("Scottish Cheese");
  break;

  case 1 :
  messageBox.show("English Cheese");
  break;

  case 2 :
  messageBox.show("French Cheese");
  break;

  case 3 :
  messageBox.show("Greek Cheese");
  break;

  case 4 :
  messageBox.show("Dutch Cheese");
         }

 }

 //Here choice==ListBox.CANCEL
 messageBox.show("Cancelled");
        }

}

Hope this helps.

Edit: Let me know if thats what you needed.

thank you very much :D

i hope i can return the favour some time... :)

the only reason i was using the mainwindow was because it was included in the template we were given...i see now that it's not needed

well, i've not bought it yet
i keep on meaning too, but the agenda always turns to pool... :rolleyes:

i've got a 100% record so far in programming anyway, so i'm not doing badly, at the moment :)

thanks again though
