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.

Scala IDE for the Eclipse plugin


Eclipse IDE does not come with Scala support out of the box. You need to install the Scala IDE plugin to add Scala compatibility to Eclipse IDE. One complication is that the installed Scala IDE dictates which Scala releases would be used in Eclipse IDE. On some occasions, it takes the Scala IDE team some time to add support for the latest Scala version. After the installation, you can switch to Eclipse's new <Scala> perspective.

Installing Scala IDE for Eclipse

While Scala IDE is available on the Eclipse Marketplace, its version is often not based on the last available version. Since the installed Scala IDE version dictates which Scala release will be supported, we recommend that you install the most stable, up-to-date version from the repository sites managed by the Scala IDE team itself.

By manually adding Scala IDE's repository, Eclipse can download and install the latest stable version. You'll need to know the Eclipse version for this. You can find...
