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.

Creating a web service in Java

We will create a simple web service in Java using the test-driven development approach. The steps that we will follow are:

  • Creating the project in Eclipse IDE
  • Modifying the Gradle build file
  • Coding the backend class
  • Coding the web service code

Creating a new Gradle project in Eclipse IDE

We will create a Gradle project and then examine the generated project.

Start Eclipse IDE if it is not already running. If necessary, acknowledge the workspace directory. This will be the root directory where Eclipse will create new projects and look for existing ones.

Eclipse IDE's Welcome tab will now be displayed. As it does not offer a shortcut for creating a new Gradle-based project, we will ignore...
