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 newtrail as part of the early access JDK 8 tutorial updates. The Date-Time APIs, coming in JDK 8, are a result of the work fromand 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 . There is also apage on migrating from the java.util date classes to the new java.time APIs. You canfrom java.net.
* Thelesson has been added to thetrail. 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. , in the Deployment trail, provide suggestions for making your RIAs less vulnerable to attack.
* A new page, , has been added to thelesson in thetrail. 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.
* Thetrail has been updated with a newlesson.
The download tutorial bundle, and the ebooks, available from the , 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 . Theand sections describe how to include these attributes in the manifest.
* Additional tips for deploying RIAs were added toand .
* Information on time stamping the signature of a JAR file were added to . 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.
