Kotlin Development

Kotlin is an object-oriented language that runs on the Java Virtual Machine. Kotlin is also a functional language, and combines the features and benefits of OO and functional programming. This course provides a fast-paced introduction to the language for developers with experience Java or similar languages (e.g. C# or C++), and then delves deeper into idiomatic uses of Kotlin in practice.

What you'll learn:

  • Writing and running Kotlin programs
  • Object orientation in Kotlin
  • Functional programming in Kotlin
  • Implementing Domain-Specific Languages
  • Using concurrency
  • Best practices and advanced techniques

Prerequisites:

Experience using Java or a similar contemporary object-oriented language.
