Kotlin Training Overview

This Introduction to Kotlin training course teaches attendees how to use all the programming features of Kotlin, refactor Kotlin codebases in IntelliJ, perform TDD using KotlinTest, and generate mock objects using Mockito. Participants also learn how to develop microservices via both Spring MVC and WebFlux and create basic Android applications.

Objective

  • Program using both the functional and object-oriented features of Kotlin.
  • Unit test and refactor Kotlin code via KotlinTest, Mockito and IntelliJ.
  • Write RESTful services in Kotlin via Spring Boot, MVC and WebFlux.
  • Create responsive mobile applications using Kotlin and Android Studio.
