Migrating to Java 6

Class Description

Class Overview

This one-day course shows Java-1.4 developers the new language features in Java 5.0, and, more importantly, illustrates best programming practices as they've been affected by these new features. This is an accelerated course that assumes long experience with earlier versions of Java. Students will leave familiar with various new bits of Java-5 syntax, and also with an understanding of the exciting new options they have for API design and general-purpose Java coding.

Class Goals

  • Take advantage of ease-of-use features including the simplified for loop, auto-boxing, and varargs.
  • Use and develop enumerated types, including those with their own state and inherent behavior.
  • Use generics effectively when coding to the Collections API.
  • Develop one's own generic types.
  • Use Java annotations as defined by other APIs, and develop one's own.
  • Understand issues of compatibility and migration in mixed 1.4/5.0 environments.
