Advanced Kotlin Programming Training Course

Course Code



21 hours (usually 3 days including breaks)


  • An understanding of the fundamentals of Kotlin


  • Developers interested in gaining a deeper knowledge of Kotlin programming


Kotlin is a modern, functional and object-oriented programming language based on Java.

In this instructor-led, live training, participants will learn how to use more advanced features that the Kotlin programming language offers.

By the end of this training, participants will be able to:

  • Understand what makes Kotlin highly extensible and unique versus other JVM languages.
  • Examine advanced topics and features in Kotlin including functions, classes, delegation, generics, metaprogramming, and asynchronous programming.

Format of the course

  • Part lecture, part discussion, exercises and heavy hands-on practice
