A complete novice- still need help please!

Question

I am a complete novice, any help would be appreciated. I have written this short programme to display two buttons in a window on screen and with a little help from Lee i have incorporated the ColorButton subclass (see below for code).
import java.awt.*;
import java.awt.event.*;
public class ButtonExample extends WindowAdapter{
private Frame mainFrame;
private Panel topPanel;
private ColorButton buttonOne;
private ColorButton buttonTwo;
// constructor
public ButtonExample(){
mainFrame = new Frame("Button Test Example" );
topPanel = new Panel();
buttonOne = new ColorButton("I'm button one");
buttonTwo = new ColorButton("I'm button two");
mainFrame.setSize( 300, 75 );
mainFrame.addWindowListener(this);
topPanel.setLayout( new FlowLayout() );
topPanel.add(buttonOne);
topPanel.add( buttonTwo);
mainFrame.add( topPanel );
mainFrame.setVisible(true);
// close the frame when clicks the close button
public void windowClosing(WindowEvent e) {
System.exit(0);
// Main program started
public static void main( String args[] ){
new ButtonExample();
I am trying to familiarise myself with subclasses and want to create a subclass of java.awt.Button to override the background and foreground colours and have come up with this
import java.awt.*;
import java.awt.event.*;
public class ColorButton extends Button{
public ColorButton(){
super();
setBackground (Color.red);
setForeground (Color.yellow);
On modifying the main programme to incorporate ColorButton it will not change the background color, only the Button color and will not display text in the buttons themselves, any suggestions would be appreciated

Answer 1

If you use the constructor:
buttonOne = new ColorButton("I'm button one");you have to write it:
class ColorButton extends Button {
   public ColorButton(String text) {
      super(text);
}
