Java event listeners. newbie

Question

hi guys
i have this simple applet with 2 threads and a scrollpane in the first thread which scrolls some test data in a textarea.
i need to add an event listener to capture the movement of the vertical scrollbar. the examples i have seen online all use a seperate class for event listening.
i was wondering if i am able to incorporate it all into this 1 class below, or must i use a seperate event listening class?
any code would be welcome! thanks in advance.
import java.applet.Applet;
import java.awt.*;
import javax.swing.*;
public class DisplayApplet extends Applet {
     public static JTextArea data = new JTextArea("", 20,100);
     public static JScrollPane dataScroll = new JScrollPane();
     public void refreshData() {
          System.out.println("refreshing data..");
     public void scrollDown() {
          System.out.println("scrolling down..");
     public void scrollUp() {
          System.out.println("scrolling up..");
     public void start() {          
          Runnable displayThread = new Runnable() {     
               public void run() {
                    System.out.println("Hello from thread 1");                    
                    data.setFont(new Font("Courier", Font.PLAIN, 10));
                    for (int i=0;i<100;i++) {
                         data.append("test\n");
                    dataScroll = new JScrollPane(data);                    
                    DisplayApplet.this.add(dataScroll);
          Runnable dataThread = new Runnable() {
               public void run() {
                    System.out.println("Hello from thread 2");                    
          new Thread(displayThread).start();
          new Thread(dataThread).start();
}

i understand your frustration, but you must also
understand that i am a java newbie. there was a time
when you didnt know any java.I only get frustrated if people don't listen to what I say, newbie or not.
im just trying to work
my way up to your knowledge and one of my initial
tasks is to write a multithreaded application with
event listeners.So go ahead.
http://java.sun.com/docs/books/tutorial/uiswing/events/index.html
may be easy for you, but it is a
little overwhelming for me as a point of entry into
java. thats all. thats why i asked if my classes were
arranged in the correct structre. i didnt know. i
need advice. i didnt say that was what i was going to
use.
any suggestions are welcome.I provided suggestions for structure. I provided suggestions for a listener to use. What else do you want?
