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
The Java Tutorials primarily describe features in Java SE 8. For
download JDK 8.
The Java Tutorials are continuously updated to keep up with changes to the Java Platform and to incorporate feedback from our readers.
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.
