请尽量使用准确的文字描述作为标题
若新帖再無恰当标题，將会被刪除

> btnExit=new Button("Eixt");
typo : Exit

> Dialog dlgConfirm;
> ...
> dlgConfirm=new Dialog();
I guess you're trying to use java.awt.Dialog. You chose a poor name for the class (rename it MyDialog or so for clarity)
And it should be:
dlgConfirm=new java.awt.Dialog(this); // check the Java API

你这个程序写得很混乱，我修改了一下你的。你看是不是你所要的：
import java.awt.*;
import java.awt.event.*;

public class Dialog extends Frame implements ActionListener
{
Button btnExit;
Button btnYes;
Button btnNo;
public Dialog()
{
btnExit=new Button("Eixt");
btnExit.addActionListener(this);
setResizable(false);

btnYes=new Button("Y");
btnYes.addActionListener(this);

btnNo=new Button("N");
btnNo.addActionListener(this);
btnYes.setBounds(new Rectangle(10,40,60,20));
btnNo.setBounds(new Rectangle(10,100,60,20));
btnExit.setBounds(new Rectangle(10,200,60,20));
this.setLayout(null);
this.add(btnYes,null);
this.add(btnNo,null);
this.add(btnExit,null);
addWindowListener(new WinCloser());
setTitle("Using a Dialog");
setBounds(100,100,300,300);
setVisible(true);
}
public void actionPerformed(ActionEvent ae)
{
Dialog dlgConfirm = new Dialog();

if(ae.getActionCommand().equals("Exit"))
dlgConfirm.show();
if(ae.getActionCommand().equals("Y"))
System.exit(0);
if(ae.getActionCommand().equals("N"))
dlgConfirm.setVisible(false);
}
public static void main(String[] args)
{
new Dialog();
}
}
class WinCloser extends WindowAdapter
{
public void WindowClosing(WindowEvent e)
{
System.exit(0);
}
}
