can't see the java code correctly....

can someone tell me what is the problem?

when using the tutorial I am trying to view the source of a given code ( in the tutorial) but the code is viewed with no LF and CR.

(I'm using windows xp).

for example:

in http://java.sun.com/docs/books/tutorial/uiswing/misc/timer.html

when viewing the code of the class ProgressBarDemo.java

a new window is opened and the code is viewed like this:

import java.awt.*; import java.awt.event.*; import javax.swing.*; /* * ProgressBarDemo.java is a 1.4 application that requires these files: * LongTask.java * SwingWorker.java */ public class ProgressBarDemo extends JPanel implements ActionListener { public final static int ONE_SECOND = 1000; private JProgressBar progressBar; private Timer timer; private JButton startButton; private LongTask task; private JTextArea taskOutput; private String newline = "\n"; public ProgressBarDemo() { super(new BorderLayout()); task = new LongTask(); //Create the demo's UI. startButton = new JButton("Start"); startButton.setActionCommand("start"); startButton.addActionListener(this); progressBar = new JProgressBar(0, task.getLengthOfTask()); progressBar.setValue(0); progressBar.setStringPainted(true); taskOutput = new JTextArea(5, 20); taskOutput.setMargin(new Insets(5,5,5,5)); taskOutput.setEditable(false); taskOutput.setCursor(null); //inherit the panel's cursor //see bug 4851758 JPanel panel = new JPanel(); panel.add(startButton); panel.add(progressBar); add(panel, BorderLayout.PAGE_START); add(new JScrollPane(taskOutput), BorderLayout.CENTER); setBorder(BorderFactory.createEmptyBorder(20, 20, 20, 20)); //Create a timer. timer = new Timer(ONE_SECOND, new ActionListener() { public void actionPerformed(ActionEvent evt) { progressBar.setValue(task.getCurrent()); String s = task.getMessage(); if (s != null) { taskOutput.append(s + newline); taskOutput.setCaretPosition( taskOutput.getDocument().getLength()); } if (task.isDone()) { Toolkit.getDefaultToolkit().beep(); timer.stop(); startButton.setEnabled(true); setCursor(null); //turn off the wait cursor progressBar.setValue(progressBar.getMinimum()); } } }); } /** * Called when the user presses the start button. */ public void actionPerformed(ActionEvent evt) { startButton.setEnabled(false); setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR)); task.go(); timer.start(); } /** * Create the GUI and show it. For thread safety, * this method should be invoked from the * event-dispatching thread. */ private static void createAndShowGUI() { //Make sure we have nice window decorations. JFrame.setDefaultLookAndFeelDecorated(true); //Create and set up the window. JFrame frame = new JFrame("ProgressBarDemo"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //Create and set up the content pane. JComponent newContentPane = new ProgressBarDemo(); newContentPane.setOpaque(true); //content panes must be opaque frame.setContentPane(newContentPane); //Display the window. frame.pack(); frame.setVisible(true); } public static void main(String[] args) { //Schedule a job for the event-dispatching thread: //creating and showing this application's GUI. javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); } }

thanks
