You're a Java developer who has heard of Scala and maybe now you’re being asked to work on Scala code. Concerned? Don’t be. Taught by Java-Scala experts Ben Evans and Julian Templeman, this courseanswers the questions you want answered: What is Scala really useful for? Does it help with concurrency? What is functional programming and how much do I really need to know? How do I set up a Scala development environment, how do I test, and what are the must-know Scala idioms? If you’re an intermediate level Java developer with six months of experience under your belt, then this course will quickly transform you from the Scala ignorant to the Scala capable.

Develop a thorough understanding of Scala and when to use it instead of Java
Learn how to use the OO features and functional features in Scala
Understand Scala’s basic syntax, pattern matching, and traits
Learn to set up a Scala development environment
Understand how to use Scala to write concurrent code
Understand the differences between the Scala and Java type systems
Master the ability to write/test Scala code and interoperate with Java code

Ben Evans is an author, speaker, consultant and educator. He is the Java editor for InfoQ, an executive committee member for the Java Community Process in London, a co-founder of jClarity, and the author or co-author of several O'Reilly titles including “Java in a Nutshell, 6th Edition,” the forthcoming "Optimizing Java," and "Java: The Legend."

Julian Templeman is a consultant, trainer and writer who has programmed systems of all types and sizes, from single-chip computers for instrumentation, up to Cray and CDC supercomputers. He heads Neuda Technologies, a London company specializing in C++, C#, Java, and Scala.
