Scala Programming

In the course Scala Programming the syntax and capabilities of the Scala programming language are discussed.

Scala Intro

The Scala Programming course starts with a discussion of the concepts and characteristics of the Scala language compared to Java. Like Java, Scala produces code that is loaded into the Virtual Machine.

Scala Syntax

Next attention is paid to the syntax, the data types, variables, control structures and packages of Scala, as well as the possibilities to extend Scala and the use of Scala Frameworks such as the Lift Web Framework and the Play Framework.

Functions and Closures

Special attention is paid to the functional aspects of Scala such as first-class functions, higher order functions and the different ways of parameter transfer in Scala. Other typical language elements of Scala are also discussed, such as closures and deferred execution.

Data Structures

Subsequently data structures and collection types in Scala such as lists, maps, tuples and their respective higher order functions are covered.

Classes and Traits

Also the object oriented aspects of Scala such as inheritance, constructors, companion objects and overriding are treated. This includes support for duck typing. The concept of Scala Traits and the use of mixins is also discussed extensively.

Pattern Matching

A separate module is dedicated to pattern matching in Scala. This includes Match expressions, Match with variables and Match with Sequences. Wildcards are also covered and it is explained how to deal with any.

Akka and Actors

Finally attention is paid to concurrency in Scala with the Akka Framework and using Actors and Mailboxes and asynchronous communication.

Audience Scala Programming Course

The course Scala Programming is intended for Java, C# and other developers who want to learn programming in Scala or who want to explore the possibilities of Scala.

Prerequisites Course Scala Programming

To participate in this course knowledge and experience with an object oriented programming language such as Java or C# is required.

Realization Training Scala Programming

The theory is discussed on the basis of presentation slides. Demos are used to clarify the concepts. The theory is interspersed with exercises. The course material is in English and a modern IDE is used.

Certification Scala Programming

Participants receive an official certificate Scala Programming after successful completion of the course.
