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.

The Scala Programming Language Training Course in Sweden

Sweden is a Nordic country that borders Norway, Finland and Denmark. The name "Sweden" originated from the "Svear", a people mentioned by the Roman author Tacitus. While being the largest Nordic country, Sweden is the fifth-largest country in Europe. Sweden has a total population of 10.4 million. The capital and largest city is Stockholm. About 15 percent of the country lies within the Arctic Circle, so that's why from May until mid-July, sunlight lasts all day in the north of the Arctic Circle. On the other hand, during December, the capital citt experiences only about 5.5 hours of daylight.

When in Sweden, visiting Stockholm's Old Town Gamla Stan, Sweden's most popular museum Vasa Museum and a UNESCO World Heritage Site; Drottningholm Palace is highly recommended.
