Introduction to Groovy for Developers

Introduction to Groovy for Developers

Bascom Bridge’s Groovy for Java Developers training teaches experienced Java developers how to write programs in Groovy that simplify, enhance, and expand their existing knowledge.

 

GROOVY TRAINING OBJECTIVES

  • Understand how dynamic languages differ from languages like Java or C#
  • Work with Groovy closures
  • Use Groovy control structures
  • Build object-oriented programs in Groovy
  • Use Groovy builders to reduce complexity
  • Access databases using Groovy
  • Process XML files in Groovy
  • Write unit tests in Groovy
  • Access Java classes from Groovy, and vice versa
  • Build a simple web application using Grails

GROOVY TRAINING PREREQUISITES

All attendees should have a good knowledge of Java techniques, including the Collections framework and JDBC.

GROOVY TRAINING MATERIALS

All attendees receive a copy of Manning’s Groovy in Action and related course materials, as well as copies of all code created during class.

SOFTWARE NEEDED FOR EACH PC:

  • JDK 1.6 or later
  • The latest stable release of Groovy
  • A powerful IDE that supports Groovy and Grails, such as SpringSource’s Groovy/Grails Tool Suite or IntelliJ IDEA
  • Related free software and lab files; please contact us for detailed specifications
  • For classes delivered online, all participants need either dual monitors or a separate device logged into the online session so that they can do their work on one screen and watch the instructor on the other. A separate computer connected to a projector or large screen TV would be another way for students to see the instructor’s screen simultaneously with working on their own.
