Need help with Math related operations...

Question

I'm learning JAVA for more than 3 weeks and I really need help...
I'm using SDK1.4 with Elixir IDE Lite (+patch installed).
In the following screenshot <http://www.geocities.com/jonny_fyy/pics/java1.png>, I've got this error (when I right-click -> Compile) . Do you know what it means & how can I solve it?
Here's how it should look if correct (pic scan from lab worksheet)... <http://www.geocities.com/jonny_fyy/pics/lab.jpg>
Here's my java file... <http://www.geocities.com/jonny_fyy/FahToCeltxt.java>
Thanks for helping :>

Hi jonny
One step ahead:
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public class FahToCeltxt extends Applet implements ActionListener {
     TextField msgField ;
     String msg = null;
     int msgValue;
     Label title;
     Button b;
     public void init() {
          title = new Label("Enter degrees in Fahrenheit: ");
          add(title);
          msgField = new TextField (10);
          add(msgField);
//          msgField.addTextListener(this);
          b = new Button("Convert");
          b.addActionListener(this);
          add(b);
//     public void textValueChanged(TextEvent event) {
//          msgValue = Integer.parseInt(msgField.getText());
//          repaint();
     public void paint (Graphics g) {
          int result = (msgValue - 32) * 5/9 ;
          g.drawString("Degree Centigrade is " + result , 50, 50);
  public void actionPerformed(ActionEvent e) {
          msgValue = Integer.parseInt(msgField.getText());
          repaint();
}Regards.
