Introduction to JVM Languages

By: van der Leun

Overview of this book

Anyone who knows software development knows about the Java Virtual Machine. The Java Virtual Machine is responsible for interpreting Java byte code and translating it into actions. In the beginning, Java was the only programming language used for the JVM. But increasing complexity of the language and the remarkable performance of the JVM created an opening for a new generation of programming languages. If you want to build a strong foundation with the Java Virtual Machine and get started with popular modern programming languages, then this book is for you. The book will begin with a general introduction of the JVM and its features, which are common to the JVM languages, helping you get abreast with its concepts. It will then dive into explaining languages such as Java, Scala, Clojure, Kotlin, and Groovy and will show how to work with each language, their features, use cases, and pros and cons. By writing example projects in those languages and focusing on each language’s strong points, it will help you find the programming language that is most appropriate for your particular needs. By the end of the book, you will have written multiple programs that run on the Java Virtual Machine and know about the differences between the various languages.

The Counterclockwise plugin for Eclipse IDE


To add Clojure support to Eclipse IDE, a plugin is required. In the Clojure world, this plugin is called Counterclockwise. It is available in a standalone version as well, which does not require an existing Eclipse IDE installation. As with all the other languages covered in this book, we will provide the installation instructions for the plugin version in this chapter. This results in one Eclipse IDE installation that will support all the languages.

It is recommended that you read Counterclockwise's documentation at http://doc.ccw-ide.org.

Installing the Counterclockwise plugin

We will use the Counterclockwise version provided on the Eclipse Marketplace. Follow this procedure to install it on your Eclipse IDE installation:

  1. From Eclipse IDE's Help menu, choose Eclipse Marketplace....

 

  1. In the search bar, enter counterclockwise and press Enter. Find the latest version of Counterclockwise that credits the Counterclockwise team and click on its Install...
