Kotlin Koans

Kotlin Koans are a series of exercises designed primarily for Java developers, to help you become familiar with the Kotlin syntax. Each exercise is created as a failing unit test, and your job is to make it pass. You can complete the Kotlin Koans tasks in one of the following ways:

Whatever way you choose to solve koans, you can see the solution for each task:

  • In the online version, click Show answer.

  • For the JetBrains Academy plugin, try to complete the task first and then choose Peek solution if your answer is incorrect.

We recommend you check the solution after implementing the task to compare your answer with the proposed one. Make sure you don't cheat!
