FirstGUI.java:7: Package java.swing not found in import.

Question

Hi,
I am currently taking JAVA at UGA and am trying to learn the GUI part on my own, since our professor is not going to cover this. This is the first error I get when I compile the program. Any help is greatly appreciated...
Thanks,
Joe
Below is the program...
/* A first GUI. This class creates a label and a button. The count in the label is incremented each
time that the button is pressed.
import java.awt.*;
import java.awt.event.*;
import java.swing.*;
public class FirstGUI extends JPanel {
     // Instance variables
     private int count = 0;          // Number of pushes
     private JButton pushButton;     // Push button
     private JLabel label;          // Label
     // Initialization method
     public void init() {
          // Set the layout manager
          setLayout( new BorderLayout() );
          // Create a label to hold the push count
          label = new JLabel("Push Count: 0");
          add( label, BorderLayout.NORTH );
          label.setHorizontalAlignment( label.CENTER );
          // Create a button
          pushButton = new JButton("Test Button");
          pushButton.addActionListener( new ButtonHandler (this) );
          add( pushButton, BorderLayout.SOUTH );
          // Method to update push count
          public void updateLabel() {
               label.setText( "Push Count: " + (++count) );
     // Main method to create frame
     public static void main(String a[]) {
          // Create a frame to hold the application
          JFrame fr = new JFrame("FirstGUI ...");
          fr.setSize(200,100);
          // Create a Window Listener to handle "close" events
          WindowHandler 1 = new WindowHandler();
          fr.addWindowListener(1);
          // Create and initialize a FirstGUI object
          FirstGUI fg = new FirstGUI();
          fg.init();
          // Add the object to the center of the frame
          fr.getContentPane().add(fg, BorderLayout.CENTER);
          // Display the frame
          fr,setVisible( true );
class ButtonHandler implements ActionListener {
     private FirstGUI fg;
     // Constructor
     public ButtonHandler ( FirstGUI fg1 ) {
          fg = fg1;
     // Execute when an event occurs
     public void actionPerformed( ActionEvent e ) {
          fg.updateLabel();
}

The error is below...
A:\ENGR1140>javac FirstGUI.java
FirstGUI.java:39: Identifier expected.
public static void main(String s[]) {
^
FirstGUI.java:39: 'class' or 'interface' keyword expected.
public static void main(String s[]) {
^
I don't think the actual error is on line 39, I looked in the book that has the code and line 39 is typed just as it is shown in the book.
Below is the program...
