About the course
Discover the power of Groovy for modern Java development. This course introduces developers to Groovy's dynamic capabilities and its seamless integration with the Java ecosystem.
Groovy underpins a surprising number of platforms and tools, such as Bosch IoT Suite, and is used in production by companies including Netflix, Sony and Google.
On our Groovy course you'll learn how to use its concise syntax to write cleaner, faster code and increase productivity.
With practical, real-world exercises and guidance from an expert Groovy instructor, you'll gain the skills to build robust and maintainable JVM-based systems.
Instructor-led online and in-house face-to-face options are available - as part of a wider customised training programme, or as a standalone workshop, on-site at your offices or at one of many flexible meeting spaces in the UK and around the World.
-
- Set up a Groovy development environment and understand Groovy's relationship and compatibility with Java.
- Write effective Groovy scripts and classes, mastering core language fundamentals, data types, control flow, and string manipulation.
- Apply Object-Oriented Programming (OOP) principles in Groovy, including inheritance, polymorphism, and the use of Traits.
- Work proficiently with Groovy collections (Lists, Maps, Ranges) and leverage powerful Closure methods for data manipulation.
- Implement robust testing strategies in Groovy, including unit testing with JUnit and advanced specification testing with Spock.
- Handle data interchange formats by parsing and generating JSON and XML data using Groovy's built-in capabilities.
- Connect to and interact with relational databases using Groovy SQL and understand the basics of ORMs like GORM.
- Automate build processes for Groovy projects using Gradle, managing tasks, dependencies, and multi-project builds.
- Develop basic web applications using the Grails framework, including controllers, views, services, and RESTful web services.
- Understand concurrency concepts and apply Groovy's features for asynchronous and parallel programming.

This course is ideal for:
Java Developers: Looking to enhance their productivity, explore dynamic language features, and leverage Groovy for scripting, testing, or build automation within the Java ecosystem.
Backend Developers: Interested in building web applications, microservices, or APIs with frameworks like Grails, or integrating with databases.
DevOps Engineers / Automation Specialists: Seeking to write powerful and concise scripts for build automation (Gradle), system administration, or data processing.
QA Engineers / Test Automation Developers: Who want to leverage Groovy's capabilities for robust unit, integration, and specification testing with frameworks like Spock.
Anyone familiar with programming concepts: Looking to learn a modern, versatile language that seamlessly integrates with the JVM.
-
A working knowledge of Java or Scala is beneficial. We can customise the training to match your team's experience and needs - with more time and coverage of fundamentals for new developers, or a swifter pace for experienced coders.
-
This Groovy course is available for private / custom delivery for your team - as an in-house face-to-face workshop at your location of choice, or as online instructor-led training via MS Teams (or your own preferred platform).
