Thinking in Functional Style

Functional Programming has been around for a while, but it is gaining popularity, especially due to direct support in languages on the JVM. Writing code in functional style is not about syntax, it is a paradigm shift. In this presentation, using examples from Java, Groovy, and Scala, you will learn how to write code in functional style. We will start out discussing the elements of functional programming and then look at examples of some common operations and how you can implement those in functional style.
