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".
The Java Tutorials primarily describe features in Java SE 7.
For best results, download JDK 7.
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 coincides with the release of JDK 7u40. Apart from fixing typos and errors, this update 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 Bulk Data Operations lesson has been added to the Collections trail. Bulk data 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.
- The JAXP trail has been updated with a new JAXP 1.5 and New Properties lesson.
The download tutorial bundle, and the ebooks, available from the Java SE Tutorial download page, have been updated for this release.
The previous release of the tutorial, which corresponded to the JDK 7u25 release, included the following:
- The JDK 7u25 release introduced 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.
-
Additional tips for deploying RIAs were added to Deployment Best Practices and Security in Rich Internet Applications.
- Information on time stamping the signature of a JAR file were 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.
