Groovy, the powerful and dynamic object-oriented scripting programming language, with static compilation and static typing capabilities for Java platform tops the list of popular OOPS languages. It integrates with any Java program smoothly and delivers robust features to your application immediately including Domain-Specific Language authoring, scripting capabilities, functional programming, and runtime and compile-time meta-programming. Groovy allows you to write code easily and combine new Java modules to the existing Java apps. It also offers simple Application Programming Interface (API) for accessing XML and Databases.

This course will not only introduce you to Groovy language but also the essential Groovy platform. Our industry expert trainers will cover all the concepts and take JVM developers from newbie to advanced level with the Groovy language through hands-on exercises, demonstration, and comprehensive lectures. The training includes real-world projects that will give you real-time experience and practical knowledge in the Groovy scripting language. At the end of this course, you will not only gain an in-depth understanding of Groovy, but you will be able to use it in a number of everyday use cases.
