Overview
Kotlin is a modern, functional and object-oriented programming language based on Java.
In this instructor-led, live training, participants will learn how to code using Kotlin as they convert an Android app from Java to Kotlin.
By the end of this training, participants will be able to:
- Understand the fundamentals of programming in Kotlin.
- Code their own Kotlin application.
- Convert an Android app from Java to Kotlin.
- Use Java from Kotlin and vice versa.
Audience
- Java developers interested in Kotlin
- Android developers interested in Kotlin
Format of the course
- Part lecture, part discussion, exercises and heavy hands-on practice
Requirements
