Java.next: Clojure, Groovy, JRuby, and Scala

In this talk, we will explore and compare four of the most interesting JVM languages: Clojure, Groovy, JRuby, and Scala. Each of these languages aims to greatly simplify writing code for the JVM, and all of them succeed in this mission. However, these languages have very different design goals. We will explore these differences, and help you decide when and where these languages might fit into your development toolkit.

As we reach the middle of our second decade of Java experience, the community has learned a lot about software development. Many of our best ideas on how to use a Java Virtual Machine (JVM) are now being baked into more advanced languages for the JVM. These languages tend to provide two significant advantages:

  • They reduce the amount of ceremony in your code, allowing you to focus on the essence of the problem you are solving
  • They enable some degree of functional programming style. Think of it as a dash of verb-oriented programming to spice up your noun-oriented programming.
