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!

• 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. The Swing release is an early release of part of the JFC. This 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.
• Added information about the 1.1 release in our To 1.1 -- And Beyond! trail.
• Made the usual fixes to broken links, typos, and other errata.

14 May 97

We improved and added more 1.1 information in existing sections. We added more examples of and information about the various types of event listeners to Handling Events. We also fixed the AroundTheWorld applet used in Writing Global Programs.

28 April 97

We added a new trail, To 1.1 -- And Beyond!, which is the headquarters for features added to the JDK after 1.0. Also, the Learning the Java Language and Essential Java Classes trails now have notes that point out material that is affected by 1.1. And finally, we reorganized our top-level files to make them more accessible.

Added a brand new trail introducing JavaBeans! This trail, JavaBeans Tutorial, written by Greg Voss, shows you the ins and outs of developing programs using the JavaBeans technology.

• Our new "guest author" program debuts in this release of the tutorial with a completely new trail about writing native methods by Beth Stearns. Check it out: Using the Java Native Interface (JNI).
• Merged copyediting changes from the book into the on-line version in these two trails: Getting Started and Writing Applets.
• Updated Writing Global Programs to work with the FCS JDK 1.1 release.
• The usual miscellaneous fixes.

Miscellaneous fixes. Also, added a new lesson describing new features of the JDK for Writing Global Programs.

This draft is the version on which the book version is based. The book and online versions aren't exactly the same -- for example, none of the copyeditor's changes have made it into the online tutorial yet. Also, the online tutorial's figures haven't been updated to be the same as those in the book. Notable content changes since the fifth draft include:

• Finished the Common Problems pages.
• Added information on the Macintosh JDK.
• Added an applet anatomy section to Getting Started.
• Improved the talk server example in the applet communication lesson.

Many pages in this draft have been rewritten or expanded upon. (If you've sent us comments and don't see them reflected in this draft, 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: The Nuts and Bolts of the Java Language and Objects and Classes in Java.
• Added new pages to the applet overview: Adding an Applet to an HTML Page and Summary.
• Beefed up the applet threads pages: Threads in Applets.
• Added a discussion of peers to the UI trail: Details of the Component Architecture.
• Added material to the native methods trail, Integrating Native Methods into Java Programs, including passing data into and out of native methods and accessing Java objects.
• Removed some trails: comparison to C/C++, troubleshooting, and tools. This information has been (or will be) incorporated into other trails/lessons.

Among the normal bug, typo and broken link fixes, this draft includes revisions to many of our old trails and lessons, plus this new material:

• Added a new lesson to Integrating Native Methods into Java Programs trail.
• Added new material to and/or wrote from scratch 4 lessons in the Writing Applets trail. Including: Creating an Applet User Interface, Communicating with Other Programs, Understanding Applet Capabilities and Restrictions, and Finishing an Applet. (The first three have since been reorganized into two trails: Taking Advantage of the Applet API and Practical Considerations when Writing Applets.

Among the normal bug, typo and broken link fixes, this draft includes revisions to many of our old trails and lessons, plus this new material:

• Added a lot of new material to Creating an Applet User Interface.

• Added a new lesson, Input and Output Streams to the Essential Java Classes trail.

• Updated links to point to new FCS1.0 JDK release.
• Fixed bugs where some applets and sources files were missing.

• Changed the name of this document from "The Java Programmer's Guide" to "The Java Language Tutorial: Object-Oriented Programming for the Internet." Why the long name? This document is going to be 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 Interface trail.

2 Oct 95 -- Released the Second DRAFT
