Advanced Kotlin Programming

• An understanding of the fundamentals of Kotlin

Audience

• 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
