The All-in-One Guide to Java Programming

Scala is an open-source language that runs on the JVM. It was developed at the Programming
Methods Laboratory of the Swiss Federal Institute of Technology (EPFL), mainly by [Martin
Odersky](http://www.scala-lang.org/node/241) (a co-designer of Java generics).

[TypeSafe](http://typesafe.com/), a private company, offers training, commercial maintenance, support, and operations
tools for Scala as well as Akka and Play.

The Scala website has the following description of the language:

> “Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and functional languages, enabling Java and other programmers to be more productive. Code sizes are typically reduced by a factor of two to three when compared to an equivalent Java application.”  - [Scala-lang.org](http://www.scala-lang.org/)
