// Java core packages
import java.awt.*;
import java.awt.event.*;
// Java extension packages
import javax.swing.*;
public class TestingLogin extends
JFrame {
private
JTextField nameField;
private
JPasswordField passwordField;
private
JButton loginButton, exitButton;
private
JLabel label1;
public TestingLogin()
{
super( "TestingLoginPage" );
Container container = getContentPane();
container.setLayout( new
FlowLayout() );
Icon nyp = new
ImageIcon( "nyp.gif" );
label1 = new
JLabel("Student Feedback System", nyp,SwingConstants.LEFT );
// construct textfield with default sizing
nameField = new
JTextField( 10 );
container.add( nameField );
// construct textfield with default text
passwordField = new
JPasswordField( 10 );
container.add( passwordField );
// register event handlers
TextFieldHandler handler = new TextFieldHandler();
nameField.addActionListener( handler );
passwordField.addActionListener( handler );
// create login button
loginButton = new
JButton( "Login" );
container.add( loginButton );
// create exit button
exitButton = new
JButton( "Exit" );
container.add( exitButton );
// create an instance of inner class ButtonHandler
loginButton.addActionListener( handler );
exitButton.addActionListener( handler );
setSize( 350, 100 );
setVisible( true );
}
// execute application
public static void main( String args[] )
{
TestingLogin application = new TestingLogin();
application.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
}
// private inner class for event handling
private class TextFieldHandler implements
ActionListener {
// process text field events
public void actionPerformed(
ActionEvent event )
{
String string = "";
// user pressed Enter in
JTextField nameField
if ( event.getSource() == nameField )
string = "nameField: " + event.getActionCommand();
// user pressed Enter in
JTextField passwordField
else if ( event.getSource() == passwordField )
{
JPasswordField pwd =
(
JPasswordField ) event.getSource();
string = "passwordField: " + new String( passwordField.getPassword() );
}
}
}
// inner class for button event handling
private class ButtonHandler implements
ActionListener {
// handle button event
public void actionPerformed(
ActionEvent event )
{
JOptionPane.showMessageDialog( null,"You pressed: " + event.getActionCommand() );
}
}
}

And, since most questions I get are actually of interest to everyone, I prefer to answer them where everyone can see the answer.
