Package Description
This is a promotional package that includes the one day technical
seminar SEM-DTJ-2762 (J2SE Platform 5.0 for the Developer: Language
Changes) and the self-paced online course WJO-2762, which has the same
title. The Web course includes lab exercises so that students can
practice what they have have learned in the seminar. This promotional
package is offered at the price of just the technical seminar.
Package Components
J2SE Platform 5.0 for the Developer: Language Changes (SEM-DTJ-2762)
The J2SE Platform 5.0 for the Developer: Language Changes course provides
students with a detailed look at the critical new features in Java 2
Platform, Standard Edition (J2SE platform) 5.0. The course topics include
generics, the enhanced for loop, autoboxing and auto-unboxing, typesafe
enumerators (enums), variable arguments (varargs), static imports, annotations
(metadata modifiers), formatted input and output (I/O), and concurrency.
Who Can Benefit
Students who can benefit from this lecture series are Sun Professional Services
consultants and architects, Sun product technical services engineers, Sun
Java programmers, Sun Global Sales Organization (GSO) sales specialists,
sales engineers, technical support engineers, and other Java developers.
