Another Simple Code Question... Please Help!

Question

Hi!
I've stumbled across another problem with my coding, and I'm hoping that someone could help me out again. I've now got two classes, one with the code to draw a button, and the other which invokes the button and does a number of other things.
I'd like it so each button is assigned to a different sound, but I get these errors when I compile...
D:\java\Phone.java:8: cannot resolve symbol
symbol : class AudioClip
location: class Phone
private AudioClip sound1;
D:\java\Phone.java:64: cannot resolve symbol
symbol : variable myButton1
location: class Phone
if (event.getSource() == myButton1)
Could anyone suggest as to why this is?? Here is the source code (I've trimmed it down for the sake of these pages...)
>>>>>>>
import java.awt.*;
import java.applet.Applet;
import java.awt.event.*;
public class Phone extends Applet implements ActionListener {
private Image image;
private AudioClip sound1;
public void init() {
setLayout(null);
image = getImage(getDocumentBase(), "phone.jpg");
sound1 = getAudioClip(getDocumentBase(), "sound.wav");
PhoneButton myButton1;
myButton1 = new PhoneButton(322,180, 1);
add(myButton1);
myButton1.addActionListener(this);
public void paint (Graphics g) {
g.drawImage(image, 0, 0, 700, 530, this);
super.paint(g);
public void actionPerformed(ActionEvent event)
if (event.getSource() == myButton1)
sound1.play();
>>>>>>>
Again, I'm sorry about the indentation.
Cheers in advance!

Answer 1

To answer your post...instance variables mean you should put your variable declarations
just below the class declaration like u have done with this...
public class Phone extends Applet implements ActionListener {
private Image image;
private AudioClip sound1;Just add here...
PhoneButton myButton1;
this.
That would make myButton1 an instance variable.
sorry, i don't understand. And now, since you've put up dukes for answering your question...you have to reward them
else they go waste. But only if you thought my reply was helpful to you. The choice is yours.
cheers.
