The Java Tutorials are practical guides for programmers who want
to use the Java programming language to create applications. They
include hundreds of complete, working examples, and dozens of
lessons. Groups of related lessons are organized into "trails".
For the most accurate and up-to-date tutorials,
please access the latest version from Sun's official website for the
Java SE Tutorials (Last Updated 5/27/2009), which can be found at:
The Java Tutorials primarily describe features in Java SE 6.
For best results, download JDK 6.
Please check out the new Java
Tutorials Community Portal, the place to discuss the tutorials, and to
share your modifications and additions to the tutorials.
The Java Tutorials are continuously updated to keep up with changes to
the Java Platform and to incorporate feedback from our readers.
Some recent updates include:
- 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 specialized trail covering Sockets Direct Protocol,
also new in JDK7.
- A new facility for gathering feedback about the tutorial. At the bottom of
each tutorial page, under the "Discuss" heading,
you can leave a publicly viewable, blog-style comment.
