I need help with some simple code! Please read!

Question

hi everyone.
I'm having problems with a piece of code, and i'd be extremely greatful if somebody could give me a hand with it. I'm totally new to java and have to make a program for my university degree, but i'm finding it extremely difficult, mainly due to my total lack of apptitude for this type of thing. I know this is easy stuff, but the books I have are no use so any help would be greatly appreciated.
I have to write a program which uses two class files. I want one with the code to produce a simple button, and one to invoke it several times at different locations. I decided to write the program as one class file at first, and thought i'd be able to split it up at later. The program works fine when it is one class file. My book said that to split the two classes up, all i needed to do was change the second class to public, although this seems to not work at all. I'm at my wits end on this, and if anyone could correct my code I'd be eternally greatful.
Here is the first class... (sorry about the lack of indentation)
>>>>>>>>>>
import java.awt.*;
import java.applet.Applet;
public class Phone extends Applet {
private Image image;
public void init() {
setLayout(null);
image = getImage(getDocumentBase(), "phone.jpg");}
public void paint (Graphics g) {
g.drawImage(image, 0, 0, 700, 530, this);
PhoneButton myButton;
myButton = new PhoneButton(20,20);
>>>>>>>
This is the second class....
>>>>>>>
public class PhoneButton {
private Button butt;
public PhoneButton(int a, int b, int c){
setLayout(null);
butt = new Button();
butt.setBounds(a,b,20,20);
add(butt);
>>>>>>>>
My compiler generates errors relating to Button, but i can't do anything to please it.
Also, could anyone give me some pointers on how to add a different number or symbol to each button. That is what I added int c for, but i couldn't get it to work.
Cheers in advance.

Answer 1

I found that there are 5 error in your code.
1. You should import the "java.awt" package to the PhoneButton.java
2. The PhoneButton is not a kind of Component. You cannot not add it to the Phone class
3. the myButton = new PhoneButton(20, 20) does not provide enough parameters to create PhoneButton
4. You cannot add a Button to a PhoneButton. Becaue the PhoneButton is not a kind of Container
Fixed code:
import java.awt.*;
public class PhoneButton extends Button {
public PhoneButton(int a, int b, int c){
     setBounds(a, b, 20, 20);
     setLabel(String.valueOf(c));
===========================================
import java.awt.*;
import java.applet.Applet;
public class Phone extends Applet {
private Image image;
public void init() {
setLayout(null);
image = getImage(getDocumentBase(), "phone.jpg");}
public void paint (Graphics g) {
g.drawImage(image, 0, 0, 700, 530, this);
PhoneButton myButton;
myButton = new PhoneButton(20,20, 1);
