Hi, I'm creating a small photo album that will read images in from an array. The applet will also have a few buttons (first, previous, next, last), which will allow the user to switch to the next photo. However, I'm a little unsure on how to write the actionPerformed statements to switch the photos, hopefully you guys can give me a few pointers. Here is the code thus far:

Code:

import java.applet.*;
import java.awt.*;
import java.io.*;
import javax.swing.*;
import java.awt.event.*;


public class Virtual_Photo_Album extends Applet implements ActionListener
{
    private Image imageArr[] = new Image [5];
    private AudioClip myAudioClip;
    private Button firstButton, previousButton, nextButton, lastButton;
    
    public void init() 
    {
       myAudioClip = getAudioClip(getCodeBase(), "../../audio.au");  // Obtians sound clip.
       myAudioClip.loop();   // Loops the audio clip.
       
           
       imageArr[0] = getImage(getCodeBase(),"../../images/image1.jpg");
       imageArr[1] = getImage(getCodeBase(),"../../images/image2.jpg");
       imageArr[2] = getImage(getCodeBase(),"../../images/image3.jpg");
       imageArr[3] = getImage(getCodeBase(),"../../images/image4.jpg");
       imageArr[4] = getImage(getCodeBase(),"../../images/image5.jpg");
    
        
       firstButton = new Button("First");     // Buttons
       firstButton.addActionListener(this);   // Assigns the ActionListeners
       previousButton = new Button("Previous");
       previousButton.addActionListener(this);
       nextButton = new Button("Next");
       nextButton.addActionListener(this);
       lastButton = new Button("Last");
       lastButton.addActionListener(this);
       
       add(firstButton);
       add(previousButton);
       add(nextButton);
       add(lastButton);
    }
    

        public void paint (Graphics g) 
        {
            g.drawImage(imageArr[0], 0, 0, this);
            g.drawImage(imageArr[1], 0, 0, this);
            g.drawImage(imageArr[2], 0, 0, this);
            g.drawImage(imageArr[3], 0, 0, this);
            g.drawImage(imageArr[4], 0, 0, this);
        }
    
    public void actionPerformed(ActionEvent e)
    {
        
    }
}
