Course Overview

This intensive one-week training program is designed for developers who want to learn Kotlin quickly with a hands-on approach. Based on Kotlin Crash Course book, the training covers Kotlin fundamentals, OOP, collections, functional programming, coroutines, delegation pattern, and unit testing.

Participants will develop hands-on projects as they learn new concepts throughout the week.

Learning Objectives

By the end of this training, participants will:

  • Gain proficiency in Kotlin’s core syntax and best practices.
  • Write clean, maintainable Kotlin code following industry standards.
  • Use null safety mechanisms to prevent common runtime errors.
  • Apply object-oriented programming principles in Kotlin.
  • Work with Kotlin collections to manage and process data efficiently.
  • Implement functional programming techniques using lambdas and higher-order functions.
  • Work with coroutines for efficient asynchronous programming.
  • Apply delegation pattern to simplify and reuse code.
  • Write unit tests in Kotlin using JUnit and MockK.
  • Develop a variety of Kotlin applications using IntelliJ IDEA and Gradle.
