Big Data Training

In response to Google’s Kotlin-first policy for Android, every team doing Android development needs to consider Kotlin. This three-day course is an in-depth introduction to the Kotlin language.

This course is appropriate for developers who already know Java and Android or those wishing to learn the Kotlin language. This course does not teach Android development fundamentals, focusing rather on the Kotlin language.

Objectives

After completing this course, students will be able to:

• Understand Kotlin language fundamentals

• Create Kotlin Classes and Objects

• Write functions and lambdas in Kotlin

• Use Kotlin Generics

• Implementing Concurrency with Coroutines
