About the training

This training was created for programming teams who are considering using Scala. The authors of the training expect from participants the basic knowledge of programming languages but not necesserily Java. Our training is a perfect introduction to the Scala. Participants will learn the advanced concepts that are connected with this language of programming. We pay a lot of attention to the practical aspects and thanks to that you will be able to use Scala as soon as you finish the training.

Scala is a language which makes use of object-oriented programming – especially functional programming – while preserving the simplicity and brevity of the code. The scalability, integration with Java, expressive syntax and a number of advanced functions are only a few features of Scala. Numerous leading companies using it on a daily basis is just another proof of its usefulness.

Who is this training for?

  • Developers
  • Java Programmers

What will I learn?

  • Learn all important features of the Scala syntax
  • New programming elements not available in other languages
  • The most important components of the Scala language such as conditional execution, loops, variables, system types, classes and methods
  • Learn how to compile programs in Scala
  • Integrate Scala with Java and get the best of two languages
  • Learn frameworks for development of applications like big data systems
  • Good programming practices in line with functional programming paradigm
  • Learn Akka and start developing powerful applications
