The Scala Programming Language was invented in 2004 in an attempt to bring functional programming to the jvm, and the java development community. It has risen to prominence in recent years as the de-facto language to compliment and replace java in existing teams, and as an advanced and capable language on greenfield projects.

Scala combines advanced techniques long established in the functional programming community with the best practices of object-orientation, allowing developers to pick and chose a style and an approach that suits their team and their problems.

By the end of this course delegates will have a clear understanding of object orientation and functional programming, and in particular, all the major features of scala which enable these styles of programming to be used and combined.

The course is divided in to 15 modules (listed in the overview) delivered over five days with an attention to an interactive Q&A-style approach to teaching and exercise practice.

Delegates must have prior programming experience in java or a related object-oriented language.
