Overview
Learning a new programming language helps to enhance your skill set as a developer, specifically so when technology is growing exponentially and developers have to update themselves constantly to stay current. One such language that is a must-learn and fast gaining momentum for developers is Groovy.
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.
Master the Groovy language with KnowledgeHut’s immersive course, and gain expertise in all the skills required to use Groovy effectively to develop different types of JVM applications.
What You Will Learn:
Installation and introduction - Learn to install Groovy using sdkman, understand the use of tools in Groovy installation
Variables - Define Groovy variables in different ways. Learn about dynamic/static typing support for variables.
Operators- Play with operators as we move forward
Functions - Learn how to define functions in the Groovy way! Implicit/explicit returns, closures and much more
Branching & Looping - Learn how to make branches in the code using selection statements, and write loops in groovy code
Object oriented programming - Learn various object oriented constructs and how Groovy achieves pure object orientation in its language design.
Object oriented concepts- Understand other object oriented concepts like composition, inheritance.
Collections - Learn to use Groovy collection data types like lists and maps.
Exception handling - Learn the use of exceptions to alter the flow of a Groovy program. Build your own custom exceptions.
Metaprogramming - Learn Groovy goodness like meta object protocol,meta class; that adds dynamacity to this programming
Builders - Build custom domain specific languages using various builders available in Groovy
Applications of Groovy - Build desktop gui applications using Groovy. Program in Groovy on Gradle to automate build tasks
Prerequisite
Exposure to any other programming language preferably Java, would be an added advantage. A little knowledge about databases and SQL would help.
Who Should Attend
- Those who want to automate day to day programming tasks using Groovy
- Java developers looking out for a JVM language that expresses more with less code
