This release of the tutorial corresponds to the JDK 8u40 release.
This release includes a new lesson in the Deployment trail that describes how to use the Java packaging tools to generate self-contained applications. Self-contained applications are Java applications that are bundled with the JRE that is needed to run. These applications are installed on a user's local drive and launched in the same way as native applications. See Deploying Self-Contained Applications for more information.
This release of the tutorial corresponds to the JDK 8u20 release. This release includes the following changes:
The Medium security level is no longer available in the Java Control Panel. To run applets locally, add them to the exception site list in the Java Control Panel. See Exception Site List for information.
A new processing limit property, maxElementDepth, has been added to JAXP. See Processing Limits for more information.
This release of the tutorial corresponds to the JDK 8 release. See What's New in JDK 8 for more information about new features in this release, which includes the following:
Lambda 表达式enable you to treat functionality as a method argument, or code as data. Lambda expressions let you express instances of single-method interfaces (referred to as functional interfaces) more compactly.
默认方法are methods in an interface that have an implementation. They enable new functionality to be added to the interfaces of libraries and ensure binary compatibility with code written for older versions of those interfaces.
Aggregate operationsenable you to perform functional-style operations on streams of elements, in particular, bulk operations on collections, such as sequential or parallel map-reduce transformations.
Date-TimeAPIs enable you to represent dates and times and manipulate date and time values. They support the International Organization for Standardization (ISO) calendar system as well as other commonly used global calendars.
Type annotationscan be used in conjunction with pluggable type systems for improved type checking, and repeating annotations enable to apply the same annotation to a declaration or type use.
Apart from fixing typos and errors, this update includes also includes the following:
The Security trail has been restructured; find security information about applets and Java Web Start applications in the Java Applets lesson.
The JDBC Basics lesson has been updated so that it is compatible with Java DB 10.10, the latest version that JDK 8 currently supports. This includes adding that DERBY is a valid option for the PARAMETER STYLE procedure element for passing parameters to a stored procedure. See Creating Stored Procedures in Java DB with SQL Scripts or JDBC API.
This release of the tutorial corresponds to the JDK 7u51 release. This release includes the following:
When signing a JAR file, time stamping the signature is recommended. A warning is shown if the signature is not time stamped. See Signing JAR Files for information.
The Type Inference section in the Generics trail has been updated with the section Target Types, which describes how the Java compiler takes advantage of target typing to infer the type parameters of a generic method invocation in JDK 8.
The Interfaces and Inheritance trail has been enhanced with information about Default Methods in JDK 8, which are methods in an interface that have an implementation. In addition, you can define static methods in interfaces.
The Collections trail has been updated with new Questions and Exercises for Interfaces and Aggregate Operations in JDK 8. These updates help you focus on some important points when working with lambda expressions, streams, and aggregate operations.
This release of the tutorial corresponds to the JDK 7u45 release. This release includes the following:
The Collections trail has been updated to recommend the preferred method of traversing collections with JDK 8: obtaining a stream and invoking its aggregate operations. 聚合操作通常与 lambda 表达式结合使用，以使用较少的代码行，使编程更具表现力。The Collection, Set, List, and Map interface pages now contain examples that demonstrate this new language feature.
Additional manifest entries are described in Enhancing Security with Manifest Attributes. The launchable examples in the Java Tutorial have been updated to use these new attributes.
This release of the tutorial corresponds to the JDK 7u40 release. This release includes the following:
We are pleased to announce the release of the new Date-Time trail as part of the early access JDK 8 tutorial updates. The Date-Time APIs, coming in JDK 8, are a result of the work from JSR 310 and provide a comprehensive model for date and time. The new trail covers the classes based on the standard ISO calendar system and includes info on converting date and time values to other calendar systems. There is also a Legacy Date-Time page on migrating from the java.util date classes to the new java.time APIs. You can download an early access release of JDK 8 from java.net.
The Aggregate Data Operations lesson has been added to the Collections trail. Aggregate operations, a new feature coming in JDK 8, iterate over collections on your behalf, which enables you to write more concise and efficient code that processes elements stored in collections.
Running rich Internet applications (RIAs) through a browser can be risky for users due to the malicious intent of others looking for vulnerabilities through which to access a user's system. Guidelines for Securing Rich Internet Applications, in the Deployment trail, provide suggestions for making your RIAs less vulnerable to attack.
A new page, Language Tag Filtering and Lookup, has been added to the Setting the Locale lesson in the Internationalization trail. This page discusses language tags, languages ranges, and language priority lists. It also includes sections about language tag filtering and language tag lookup, with plenty of examples that you can compile and run.
This release of the tutorial corresponds to the JDK 7u25 release. The JDK 7u25 release introduces new JAR file manifest attributes that are used to defend Rich Internet Applications (RIAs) against unauthorized code repurposing. The Permissions and Codebase attributes are described in Enhancing the Security of the JAR File. The Deploying an Applet and Deploying a Java Web Start Application sections describe how to include these attributes in the manifest.
Information on time stamping the signature of a JAR file has been added to Signing JAR Files. Depending on the security level set in the Java Control Panel, RIAs that have an expired certificate might not be allowed to run. However, if the signature is time stamped and the time stamp shows that the certificate was valid when the RIA was signed, the RIA is allowed to run.
The Deployment ebook (both mobi and epub formats) has been updated for this release.
This release of the tutorial corresponds to the JDK 7u21 release. The JDK 7u21 release enables users to make more informed decisions before running Rich Internet Applications (RIAs) by prompting users for permission before an RIA is run. The prompt contains information about the certificate used to sign the app and the level of access requested by the app. Depending on the security setting in the Java Control Panel, some apps might be blocked from running.
The tutorials were updated to reflect the recommendation that all RIAs be run from signed JAR files. A new page has been added to the Deployment trail on User Acceptance of RIAs. You may also want to refer to the lesson on Signing and Verifying JAR Files. Finally, all Java Web Start examples launched from within the tutorial are now signed and all applets run within the sandbox.
Another feature coming to Java SE 8 is the ability to invoke methods that use the fork/join framework to sort arrays in parallel. The Arrays and Fork/Join pages have been updated with information on manipulating arrays.
The Annotations page has been moved and expanded to be a full Annotations lesson. The new lesson includes information on Java SE 8 features: Type Annotations, which can be used in conjunction with pluggable type systems for improved type checking, and Repeating Annotations. This early access lesson is available online only.
This update heralds the release of the Java Tutorials in two ebook formats:
mobi ebook files for Kindle. For best results we recommend viewing on the Kindle Fire or Kindle DX.
ePub ebook files for iPad, Nook, and other eReaders that support the ePub format.
Each ebook contains a single trail. You can download trails via the link in the "In Book Form" box on the Java Tutorials home page.
For best results when viewing preformatted code blocks, adjust the landscape/portrait orientation and font size of your device to enable the maximum possible viewing area.
We are pleased to announce that the Preparation for Java Programmer Language Certification lesson has been completely reworked. The objectives for each Java SE 7 certification exam are listed and links are provided to relevant tutorial pages.
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.
switch 语句page has been updated to reflect the ability to switch on a String object.
The Diamond Operator has been added to generics. See the
Type Inference section for more information.
Using non-reifiable parameters with varags methods is also new.
See Using Non-Reifiable Parameters with Varargs Methods for more
information.
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.
18 Oct 2010 -
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:
自定义加载体验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.
开发可拖动的 Applet–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.
27May 2009 -
This update features:
An entirely reworked File
I/O lesson, featuring NIO.2. This functionality is part of
JDK 7.
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:
如何使用图标, with an updated demo by reader Collin Fagan.
*OK, we made this up, or rather Collin did. :-)
National Honesty Day, 30 April 2007 -
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 -
The 1.4 version of the Java 2 Platform Standard Edition was
released recently. We're in the process of updating the Creating a GUI with JFC/Swing trail to
1.4. The Full-Screen
Exclusive Mode API covers a brand new API in the 1.4 release;
programmers who write games or other graphic-intensive applications
should read this trail.
Lots of miscellaneous fixes to broken links and typos.
Underdog Day (World), 19 December 01 -
Maintenance Release
We removed our survey from the Web site. We want to thank
everyone for their thoughtful responses. Your feedback will help us

future. We've also included some localization questions to help us
learn what languages you'd like us to provide translations in.
Lots of miscellaneous fixes to broken links and typos.
Golden Week (Japan), 3 May 01 -
New lesson! User Interfaces that Swing: A Quick Start Guide. is
a quick start guide to using Swing components to build user
interfaces. It is built around several progressively complicated
examples. (This lesson started life as a chapter in our latest
book, The Java Tutorial, Third Edition.)
Another new lesson! For programmers who write games or other
graphic-intensive apps, check out the new Full-Screen Exclusive Mode API
lesson. This API will be included in the 1.4 release of the Java 2
Standard Edition.

Added Werner van Mook's Mac adaptation of the instructions for
writing and compiling your first programs: First Cup of Java (Mac
OS).
Added feedback form. Please use this form to contact us instead of sending
mail directly. It will help direct your mail to the right
person.
Modified our tools to provide automatic next and previous
links, automatic page titles, and automatic page headers and
footers. This change should be largely unnoticeable to readers
except that these page elements should contain fewer errors and
inconsistencies.

pages. This change should be largely unnoticeable to readers except
that these pages should contain fewer errors and
inconsistencies.
Fixed various broken links, typographical, and other
errors.
Put all of the images on the Swing Components Visual
Index.
Updated API links to point to Java 2 SDK docs.
Thanks to our two delightful summer interns, Ray and Indra, we
were able to do a lot of clean up including fixing omissions,
making clarifications, adding examples, and so on.
We did a pass and cleaned up most of the pending issues. The
only remaining pendings are in the BINGO lesson, which has not been
completed, and in one of the book pages for the Second Edition. We
hope, but do not promise, to clean up the remaining ones for the
next tutorial update.

We made some changes to our new page format in resonse to reader
feedback.
Because of reader feedback, we added a navigation area to the
bottom of each page.
Implemented a max width of 460 for images to prevent large
images from creating a page that is too wide.

Saturnalia, 22 December 97 - The long awaited
update!
This is a major update of the tutorial. 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.
Got a totally new JavaBeans Tutorial by Andy
Quinn!
8 July 97 -
One of the goals of the tutorial is to document the latest and
greatest from JavaSoft as it is released. To this end,
we've added a lesson about Using Swing Components.

information is only available from the Java Tutorial.
Added a trail, Java Security 1.1, covering the
new 1.1 security APIs.
Updated the The JavaBeans(tm) Tutorial by Greg Voss.
Promoted Writing Global Programs to a trail.
This trail is still in progress, but it contains new material
including several excellent demos from
Taligent.

published as a book, and we wanted to make sure the title 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.
Added a new lesson, Laying Out Components Within a
Container, in the Creating a User

work and how you use the Applet class to create an applet.
The new Creating a User Interface trail has
two new lessons: Overview of UI Elements which
introduces you to the objects that the Java development environment
provides for building UIs, and Laying Out Components within
a Container which tells you how to use each of the
Components provided in the AWT.
We've also added the Integrating Native Methods into
Java Programs trail that shows you how to integrate native
methods into your Java programs.
