Set default Button and provide a KeyEvent to a component with focus !!!

Question

What is to do ???
I have following program:
public class DefaultButton extends Frame implements ActionListener
     private Button close;
     public DefaultButton()
          super("Default-Button");
          setLayout(null);
          setSize(400, 200);
          setLocation(150, 100);
          setBackground(Color.lightGray);
          addWindowListener(new WindowAdapter()
               public void windowClosing(WindowEvent e)
                    setVisible(false);
                    dispose();
                    System.exit(0);
          // CloseButton
          close = new Button("Close");
          close.addActionListener(this);
          close.setVisible(true);
          close.setSize(100, 30);
          close.setLocation(290, 160);
          add(close);
          setVisible(true);
     public void actionPerformed(ActionEvent e)
          String cmd = e.getActionCommand();
          if (cmd.equals("Close"))
               setVisible(false);
               dispose();
               System.exit(0);
     public static void main(String [] args)
          DefaultButton wnd = new DefaultButton();
}If I click on "Close"-button, the window will be closed. But, if the button "Close" has focus, it schold be possibile to close the window with a press on the Enter-Key? How to do it? How can I provide an KeyEvent to button "Close"?
Tanks for any help.

Hi pitalica!
It is possible using KeyListener:
public class DefaultButton extends Frame implements ActionListener, KeyListener {
close.addKeyListener(this);
public void keyPressed(KeyEvent e) {
if ((e.getSource() instanceof Button)
&& (((Button) e.getSource()).getActionCommand == "Close")) {
int kc = e.getKeyCode();
if (kc == KeyEvent.VK_ENTER) {
performs any action
public void keyTyped(KeyEvent e) {}
public void keyReleased(KeyEvent e) {}
I hope it helps.
