In this chapter, we have covered how to start integrating Scala code into a Java codebase as well as how to refactor some of the most common Java constructs into Scala by following some style guidelines. A much more exhaustive list of style recommendations is available at http://docs.scala-lang.org/style/ if you are interested in learning more.

So far we have been mostly addressing the Scala language and syntax. In the next chapter, we are going to introduce the tools that complement it and that are necessary to make our Scala programming both productive and enjoyable.
