Groovy Programming Fundamentals Training in Marina Bay, Singapore

Groovy is a powerful, optionally typed and dynamic language, with static-typing and static compilation capabilities, for the Java platform. This course is designed to introduce participants to the Groovy programming language from the ground up. It covers syntax, scripting, object-oriented capabilities, functional features, and its integration with Java. Groovy is often used in automation tasks, scripting for Jenkins, test automation (e.g., Spock framework), and rapid prototyping.
