[Madhan Kumar]

Hi, i am developing a chat application using sockets.I have used two panels in a frame. My problem is that the button in panel isnt working, i have used the same action event for both the panels.. i am adding here the part of my code..

 import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.util.*;
 
public class Fpage extends Frame implements ActionListener
{
JFrame frame;
        JPanel p2;        
        JLabel lheader;        
        JButton buser;
        JButton bguest;
       
public Fpage()
{frame =new JFrame("Choose your option");
  p2=new JPanel();
    p2.setLayout(null);    
    frame.getContentPane().add(p2);    
    lheader = new JLabel("WELCOME");
Font font = new Font("Courier", Font.BOLD, 26);
lheader.setFont(font);
JButton buser=new JButton("Users");
        JButton bguest=new JButton("Guests");
        
        lheader.setBounds(135,50,320,35);
        
        buser.setBounds(50,180,140,30);
bguest.setBounds(210,180,140,30);

String tu="Already a user? click here";
        String tg="Come in Guests";       
        buser.setToolTipText(tu);
bguest.setToolTipText(tg);
p2.add(lheader);
p2.add(buser);
p2.add(bguest);
frame.setSize(400,300);
 frame.setVisible(true);
p2.setSize(400,300);
p2.setVisible(true);
bguest.addActionListener(this);
buser.addActionListener(this);
}
public void actionPerformed(ActionEvent e)
{
if((e.getSource())==buser)
{
JOptionPane.showMessageDialog(p2,new String("USER"));
}
else if((e.getSource())==bguest)
{
JOptionPane.showMessageDialog(p2,new String("GUEST"));
}
}

public static void main(String args[])
{
Fpage f=new Fpage();
}
}

My button when clicked has to display corresponding dialog box, but it fails to do so, what could be wrong please help. thanks in advance

change
JButton buser=new JButton("Users");
to
buser=new JButton("Users");

(Youre declaring buser as a local variable inside
the constructor. You need not declare it locally, because
you want it to reference the gloable instance.)
