Help needed regarding buttons and action listeners!

Question

Hey,
Im designing an applet and im trying to create it so that when a button is pressed a new Draw object is drawn, I have read up about action listeners but im not totally sure where they need to be inserted
Ive posted my code below so hopefully someone out there wll be able to see what im working with!
Thank you in advance
public class ImageWithMulti extends Applet {
    Image image;
    public void init () {
        image = getImage(getDocumentBase(),
            getParameter("Channel"));
    public void paint(Graphics g) {
        g.drawImage(image, 0, 0, this);
        drawMultiDown1
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);   //2nd number changes left sided position up or down
        drawMultiUp1
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);
        drawMultiUp2
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);
        drawMultiDown2
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white); 
        drawMultiUp3
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);   
       drawMultiDown3
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);
       drawMultiUp4
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);
       drawMultiDown4
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);
       drawMultiUp5
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);

hi,
i've modify your code. but i've commented your some original code because i was getting error...
please check the code...
import java.awt.event.*;
import java.applet.*;
import java.awt.*;
  <applet code="ImageWithMulti.class" width=100 height=140></applet>
public class ImageWithMulti extends Applet implements ActionListener {
    Image image;
    Button btnClick = null;
    public void init () {
        /*image = getImage(getDocumentBase(),
            getParameter("Channel"));*/
          btnClick = new Button("Click");
          add(btnClick);
          btnClick.addActionListener(this);
    public void paint(Graphics g) {
        g.drawImage(image, 0, 0, this);
       /* drawMultiDown1
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);   //2nd number changes left sided position up or down
        drawMultiUp1
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);
        drawMultiUp2
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);
        drawMultiDown2
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white); 
        drawMultiUp3
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);   
       drawMultiDown3
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);
       drawMultiUp4
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);
       drawMultiDown4
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);
       drawMultiUp5
    (g, 0, 0, getSize().width, getSize().height, 25, new Color(0).white);*/
     public void actionPerformed(ActionEvent ae){
          if(ae.getSource() == btnClick){
               System.out.println("Hey");
