This update coincides with the release of JDK 7. Most of the JDK 7
features have already been added to the tutorial.
This release includes the new deployment page,
Deploying without Codebase.
A summary of what has been added for the JDK 7 release:
The Internationalization trail has been updated to reflect the updates as a result of the Unicode 6.0 work. For a list of the affected sections, see the 21 Feb 2011 entry.
The JDBC Basics lesson of the JDBC trail has been completely reworked and updated.
As of JDK 7 build 130, the NIO.2 File I/O package has
been updated, with new and simplified API. The
File I/O (Featuring NIO.2)
section has been modified to reflect these changes.
Samples that demonstrates how to use RowSet objects
have been added to the JDBC trail.
Please see Using RowSet Objects
for more information. In addition, a sample that shows you how to integrate
JDBC with a GUI API, in particular the Swing API, has been added.
Please see Using JDBC with
GUI API for more information.
As a result of
Project Coin,
several changes were introduced to the Java language:
The Primitive
Data Types page has been updated to discuss binary literals
and to mention that underscore characters can
appear anywhere between digits in a numerical literal.
The switch
Statement page has been updated to reflect the ability to
switch on a String object.
The ability to catch more than one type of exception with a single
exception handler has been added. See
The catch
Blocks for more information.
The try-with-resources statement ensures that a resource
(such as a BufferedReader) is closed when the program is
finished with it. See
The
try-with-resources Statement for more information.

This update features:
For several months the Java SE Tutorials were not available as a
download. We are happy to report that the very popular bundle
is back and available through on the front page
through the link under the "Tutorial Resources" box to the right.
Do the Java Tutorials seem overwhelming to you? We have
added a new Learning Paths page.
The new Fork/Join page,
part of the Concurrency
lesson, describes how you can use the Fork/Join framework to take
advantage of multiple processors.
This feature is available now in the Java SE 7 release available on
java.net.
The JDBC Basics lesson has been completely
revamped, including updated sample code that you can download,
compile, and run – the code has been configured for Java DB and MySQL.
See Getting Started
for more information.
Finally, a small, but notable, change is that the standalone JNDI tutorial,
previously available on java.sun.com, has been moved to the Java SE
documentation archive on
docs.oracle.com
and many broken links in the tutorial have been fixed.
The front page of the JNDI tutorial
has been modified accordingly, and redirects are in place ensuring a
seamless transition.
7 July 2010 —
This tutorial update represents the first release under its new
home at docs.oracle.com. Redirects are in place,
so any attempt to access the tutorials at
java.sun.com/docs/books/tutorial will be redirected to the new
location. We hope this will be a seamless transition for our many
tutorial readers,
but please let us know if you encounter any problems.
Also included in this release:
Customizing the Loading Experience explains how to provide a customized
loading progress indicator for a rich Internet application,
a feature first introduced in the JDK 6 Update 18
release and enhanced in the Java SE 6 Update 21 release.
Developing
Draggable Applets – a new topic describing
how to create an applet that can be dragged outside
of a browser and dynamically converted into a Java Web Start
application.
Previously, a number of the Swing
examples, which are distributed as NetBeans projects,
were missing a tag that prevented them from being
opened in NetBeans 6.5 or later. The missing tag has been added to
all project.xml files.
Various minor errors, typos, and broken links have been fixed.
23 September 2009 —
This update features:
A Deployment tutorial that covers a wide range of topics about the development
and deployment of rich Internet applications. The Deployment tutorial contains the
following lessons:
A new Interfaces and Inheritance page discussing
Polymorphism.
As always, we have fixed numerous bugs, typos and broken links.
27 May 2009 —
This update features:
An entirely reworked File I/O
lesson, featuring NIO.2. This functionality is part of JDK7, which is available
now through the Open JDK
project on java.net.
A new facility for gathering feedback about the tutorial. At the bottom of
each content page, you can leave a publicly viewable comment.
Leaving a comment using the JS-Kit
mechanism is similar to leaving a blog comment. Let us know what you think!
The Drag and Drop lesson has
been completely rewritten and updated to JDK 6.
An updated Copyright page.
A new License page that allows
our users to modify tutorial content for limited non-commercial
purposes.
We are moving our downloads to the Sun Download Center.
You are required to accept the license in order to download
the Java Tutorials.
We are retiring the feature where we name the releases and will
be using dates from now on.
Besides the work listed here, there are many fixed broken links,
typos and other miscellaneous errata.
Antediluvian Chili Pepper Day*, 1 August 2007 —
This push completes the tutorial update to JDK 6, with the exception of
the Swing drag and drop lesson, which is marked as such. There are many updated
pages, but the more notable changes are:
This update focuses on the Swing tutorial — we have updated 80% of the
material in the Swing tutorial to the JDK 6 release.
A significant part of this effort makes our examples easier than ever to use!
The Swing examples are now packaged ready to use in NetBeans IDE. Check out the
examples index
for any of the Swing lessons (this link takes you to the Components lesson, there
is a separate index for each Swing lesson)
and you can download a zip file for any demo.
Or you can visit the Check out the
Running Tutorial Examples in NetBeans IDE page
for more information on how to use the examples with NetBeans. Visit the
NetBeans IDE download page
to obtain release 5.5 of NetBeans IDE (it's free).
Some of our brand new and significantly updated sections include:
The Java™ Tutorial (4th edition) is now available in print. This update of the tutorial includes an Errata page for the first printing. Our publisher, Addison Wesley, informs us that several translations of this book are already in progress.
For this update, all of the specialized trails, except for Reflection,
have been updated to release 6. The newly updated sections include:
The new look and feel of the tutorial has been further refined.
Many of you have sent us feedback and we have been listening.
The TOC on the left-side of the page can now be toggled.
See the "Hide the TOC" button in the banner at the top of the page.
The core tutorial is now updated to release JDK 6.
This is in preparation
for a new printed edition of
The Java™ Tutorial (4th edition) that you can pre-order on Amazon or through many other booksellers.
This online update includes the following sections:
Swing, a new trail that shows the
many capabilities of Swing and features a sophisticated
PasswordStore demo by Swing engineer, Scott Violet
(source included)
All examples in the basic tutorial and in the Swing tutorial have
been updated to compile against the 6.0 release.
Applets and Java web start applications
require 6.0 to run. (The one exception are the applets in the
deployment/applet section that will run under 1.4 and 1.5.)
You may notice that some very old parts of the tutorial have been
removed. The previous version of the tutorial is now available
via download. See the download page.
Finally, the tutorial itself has gotten a facelift, with a new look and feel. Let us know what you think about these changes and please let us know if you find any problems. Send feedback via our feedback form.
Nutcracker Release, 23 December 2005 —
The Java Tutorial update to JDK 5.0 is now complete.
This includes these sections of the tutorial:
Several of the very old, out-of-date sections have been
archived and are now available via download. See the
download page for a complete
list of available bundles.
You'll notice that the old applet and JAR sections have been
updated and moved to the new Deployment trail. You may notice
redirects if you have absolute links to the old pages.
We fixed the broken search feature:
it wasn't limiting its search to the tutorial. This is now
working correctly.
Across the tutorial, 1.0 and 1.1 examples have been removed.
The release 5 examples are located in "ex5" directories.
We have a new
feedback
form. It looks different, but your feedback goes to the same
place. Although our workload prevents us from responding to each
email, rest assured we do read it.
Finally, we fixed the usual broken links, typos, and other errata.
At readers' request,
we changed the Feedback Form link at the top of each window
to bring up a new window
so you don't lose the page you're giving feedback about.
We started adding ZIP files so you can easily download
all the examples for a particular chapter.
We added 5.0 versions (including web start links)
of the examples in two Swing lessons: Getting Started with Swing
and Learning Swing by Example.
We moved several applets back to the pages where they're
referred to. Please
let
us know how you feel about this. Another alternative
for some of these that aren't truly integrated with their page
is to make them web started applications.
We made many small changes — which you probably won't notice
— to clean up our HTML, reduce code sample line length where
necessary,
and generally enable better generation of book files from the HTML files.
Finally, we fixed the usual broken links, typos, and other errata.
Anya's Birthday Release, 14 Feb 2005 —
The following sections have been updated to 5.0 (though most are still
pending engineering review):
Other, minor changes that you might notice include:
In the chapters where the content hasn't yet been updated,
we have updated some of the images. In some cases, this might lead
to a mismatch between the text (or code) and the image.
We have modified the page headers and the copyright notices.
This will cause each page to be updated, even if the content hasn't
yet changed.
Our search page has been fixed.
Thanks to those of you who reported that it was broken.
Finally, we fixed the usual broken links, typos, and other errata.
Swing Book Release #2, 11 March 2004 —
Added an information page for our just-published book,
The JFC Swing Tutorial, Second Edition.
It includes pointers to other pages
describing and book and CD contents,
as well as errata.
Added questions and exercises, along with answers,
to the Swing trail.
These reflect the Questions and Exercises section
at the end of every non-reference chapter in the new book.
Updated the
table sorting
example
to use a much more recent, functional, and robust version
of TableSorter.
Throughout the tutorial,
made the usual fixes to broken links, typos, and other errata.
Maya's Birthday Release, 3 November 03 —
With the exception of the first two lessons,
the Swing trail
has now been updated to 1.4
(with notes about what's expected in 1.5)
and reflects what will be published in the upcoming book.
We'll note the biggest changes here,
but with so many changes, we can't mention them all.
After consulting with the Swing engineers,
we changed our thread safety recommendations
and updated all but a few straggling 1.4 Swing examples
to be thread safe.
The newest recommendation is this:
Build the GUI on the event-dispatching thread.
See How to Use Threads for details.
Updated all pages in the Swing
layout
and
events
lessons to 1.4.
Updated the accessibility, actions, threads, and timer pages in the
Using Other Swing Features
lesson to 1.4.
In the
Using Swing Components
lesson,
updated the applet, root pane, spinner, split pane, tabbed pane,
table, tool bar, tool tip, tree, and all text component pages
to 1.4. Created pages for separators and formatted text fields.
Completely rewrote the painting
lesson.
Instead of featuring only the API in the Graphics class,
it now simply tells you what's special about painting Swing components
and refers you to the 2D trail for details.
Throughout the tutorial,
made the usual fixes to broken links, typos, and other errata.
Victoria Day (Canada), 19 May 03 —
Added two completely new and
much-requested pages to the Swing part of the tutorial:
How to Use Data Transfer
(which covers drag and drop and cut/copy/paste) and
How to Use the Focus Subsystem.
Many thanks to Shannon Hickey and Scott Violet for their reviews
of these rather long and technically complex sections.
Drastically changed the text and examples for
How to Use SpringLayout.
It's still unfinished, but should now be more useful.
Many of the
examples
use a SpringUtilities class
that makes it easy to build grids of cells,
including columns of label-text field pairs.
Updated a couple of other Swing reference pages to 1.4:
borders, icons.
Updated applet tags throughout the tutorial to use APPLET
instead of OBJECT/EMBED.
This should make them execute successfully in
recent versions of Java Plug-in.
Changed a couple of applets to use getResourceAsStream
instead of getResource to load their images —
this is more efficient for applets using Java Plug-in.
Throughout the Swing examples,
invoked setOpaque(true) on
JPanels used as content panes,
to account for the fact that
panels are no longer opaque by default
in every look and feel we distribute.
(GTK+, added in 1.4.2, has transparent panels.)
Where possible, changed examples that use
p = new JPanel(); p.setLayout(l)
to use p = new JPanel(l),
to avoid the unnecessary creation
of FlowLayout objects.
Rewrote and reorganized much of the early part of the
Swing components lesson.
This included adding two new pages,
with some new material and some extracted from other pages:
Using HTML in Swing Components and
Using Models.
Miscellaneous fixes to broken links, typos, and the like.
Year of the Black Sheep (China), 3 February 03 —
Reorganized and updated Setting the Look and Feel.
It even has information on the GTK and Windows XP look and feels,
which will be introduced in 1.4.2.
Added source code for the 1.4 events demos.
We had released the demos in runnable form soon after our last update,
but without the source code.
Updated/added examples in the components lesson.
New demo: FrameDemo2. Added PNG support to FileChooserDemo2.
Changed ListDemo to not add a person if they already exist.
Added a text input dialog to DialogDemo.
Updated our standard headers and footers to be more usable
by people with disabilities. These changes should be invisible
to our other readers.
Miscellaneous fixes to broken links, typos, and the like.
Onion Market Day (Switzerland), 25 November 02 —
We changed our external links to bring up new, blank windows
instead of named windows. Although this might result in
an excess of windows, it should solve the problem of people
losing the named windows.
We added many 1.4 examples to two of the Swing trail's lessons:
Using Swing Components and Using Other Swing Features.
These examples can be launched using
JavaTM Web Start,
and the source files now list what other files they need.
The overall Swing example index
now points to all versions of the examples for each lesson.
We added a page on
key bindings
to the Using Other Swing Features lesson.
We also updated the
action
and
accessibility pages.
In the Swing components
lesson,
we changed the order of the pages and updated all the pages
up through and including buttons.
We're still in the process of updating the
Creating a GUI with JFC/Swing trail to
1.4.
You might notice some changes or notes about changes we plan to make.
We added a Java Web Start page
to help people install and use that software.
Miscellaneous fixes to broken links and typos.
Robinson Crusoe's Birthday, 30 September 02 —
We added a new lesson!Regular Expressions
covers the java.util.regex API introduced in the
1.4 release of the
Java™ 2 Platform Standard Edition.
Regular expressions can be used as a tool to search, edit, or manipulate text or
data. This package uses Perl-like syntax,
but our lesson doesn't assume that you've had previous experience with
regular expressions.
The Tutorial front page has completely changed,
and the java.sun.com
one now looks different from the downloaded one.
The content of the two pages remains nearly identical.
We retired the Servlets trail, since it's out of date
and other tutorials have updated servlet coverage.
For links to the newer coverage
and to a downloadable form of the old trail,
see the old trailhead.
We added a page of printing tips:
Improving Printing Performance.
It includes strategies that you can use starting
in both 1.3 and 1.4.1.
We added a file describing the license for our code examples.
Unless otherwise licensed, all our code is available under this
license.
Notice is hereby given: We plan to
retire the Trail Map.
We're in the process of updating the
Creating a GUI with JFC/Swing trail to
1.4.
You might notice some changes or notes about changes we plan to make.
Lots of miscellaneous fixes to broken links and typos.
Magha Puja Day (Thailand), 4 March 02 —

Almost every file has been touched in some way.
This release of the online tutorial corresponds with the
release of the 2nd edition of The Java Tutorial book
and is the version of the online tutorial that appears on
the CD-ROM that accompanies that book.
The changes are in progress, but to a large extent
we have integrated 1.1 information into
the existing trails, lessons, and examples. This is
in sharp contrast to the 1.1 notes that were littered
throughout the previous version of the tutorial and
were, admittedly, somewhat confusing.
Also, we are in the process of integrating copyedit and
other changes made to the book version, into the online version.
This has been completed thoroughly in some areas of the online
tutorial, and spottily in other areas. We will continue
with this process throughout the coming months.
New lessons in this tutorial that first appeared in print
in the 2nd edition of The Java Tutorial book:
The Java Phenomenon
Migrating to 1.1
A Preview of Things to Come
New trails for this version of the tutorial
that haven't yet made it to print:
Added a Putting It All Together trail
that provides a large, real-world, client/server example and analyzes it.

please don't be insulted —
we haven't finished incorporating reviewer comments.)
Some of the notable changes include:
Revised Application Anatomy lesson
and moved it to the Getting Started trail:
The Anatomy of a Java Application.
We plan to write an equivalent section
for applets.
Did major rewrites of the following lessons in the Java trail:

was as descriptive as possible,
without requiring much prior knowledge of the potential buyer.
Added ALT text to our link graphics,
so that people using non-graphical browsers
can understand the information the graphic was conveying.
