Introduction to Kotlin Turkmenistan Eğitimi

This is an intensive course for developers moving to Kotlin from Java, C# or similar languages. It is designed to be conducted over four days but can be tailored based on the requirements of the delegates. The delivery is workshop based with delegates spending the majority of their time solving problems and creating sample applications.

By the end of the delivery delegates will be able to program using all the features of Kotlin, refactor Kotlin codebases in IntelliJ, perform TDD using KotlinTest and generate mock objects using Mockito. Additionally they will be able to develop microservices via both Spring MVC and WebFlux and create basic Android applications.

Delegates must be confident Java developers, or else have equivalent experience in languages like Groovy and Clojure. Knowledge of Functional Programming concepts is very helpful but not essential. If the chapters on Spring Services and Mobile Development are being covered then delegates should have prior experience with those frameworks.

• 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
