JVM languages - Scala, Groovy, Grails, Jruby
The Java platform is highly robust because the Java Virtual Machine (JVM) supports much more than just the core Java language. Application developers need to choose which of the JVM languages to run on the virtual machine. Scala, Groovy, Grails, and Jruby are all popular choices.

The Grails framework leverages Groovy under a "coding by convention" paradigm. Learn about all of these Java languages and more in this topic section.
