Course description

There a few significant updates to Java SE 7 in the area of XML. JAXB, JAX-WS and JAXP all had a minor revision update which included a number of bug fixes, localization updates, and standardization of data mapping. JAXP also got some additional security updates to guard against denial of service attacks that exploit XML processing. In the internationalization or I18N area, Java SE 7 was all about support for Unicode 6.0. Support for international stands, like the ISO 4217 currency codes and locale updates adding support for IETF-BCP 47 language tags, the Unicode data markup language, and adding a couple new locale default objects to control formatting resources and the UI. The new numeric shaper enumerated range class adds new Unicode ranges and makes outputting numbers in different shapes a breeze. The last topic in the course covers the updates to the collections framework. The framework got two new concurrency queuing classes and was tuned up with a new hash function for maps and a new sorting algorithm which affects the entire framework. These algorithm upgrades will speed up your application without a single change to your code.


This course assumes users have a solid understanding of object-oriented principals and experience coding with Java 5 or greater. This course was filmed using Eclipse for RCP and RAP developers (Java developer edition). A general understanding of Eclipse is required but only to understand the methods shown. The theory for this course will work on any IDE that supports the Java 7 SE SDK. You should have viewed the Java 7 SE: Enhancements and Concurrency and Java 7 SE: IO, New IO and Network Protocols courses before viewing this course.
