The sixth official language on the Heroku polyglot platform is Scala, available in public beta on the Cedar stack starting today.

Scala deftly blends object-oriented programming with functional programming. It offers an approachable syntax for Java and C developers, the power of a functional language like Erlang or Clojure, and the conciseness and programmer-friendliness normally found in scripting languages such as Ruby or Python. It has found traction with big-scale companies like Twitter …

We're pleased to announce the public beta of Heroku for Java. Java is the fourth official language available on the Cedar stack.

Java is, by many measures, the world's most popular programming language. In addition to its large and diverse developer base, it offers a huge ecosystem of libraries and tools, an extremely well-tuned VM for fast and reliable runtime performance, and an accessible C-like syntax.
