An applet can display images of the format GIF, JPEG, BMP, and others. To display an image within the applet, you use the drawImage() method found in the java.awt.Graphics class.
Example: - To Display image in Applet
import java.applet.Applet;
import java.awt.Graphics;
import java.awt.Image;
public class DisplayImageExample extends Applet
{
Image img1, img2;
public void init(){
img1 = getImage(getDocumentBase(), getParameter("Image1"));
img2 = getImage(getDocumentBase(), getParameter("Image2"));
}
public void paint(Graphics g){
//display an image using drwaImage method of Graphics class.
g.drawImage(img1, 0,0,this);
g.drawImage(img2, 100,100,this);
}
}

audioClip = getAudioClip(getCodeBase(), "image.wav");
}
public void actionPerformed(ActionEvent ae){
Button source = (Button)ae.getSource();
if (source.getLabel() == " Play in Loop "){
audioClip.play();
}
