Nice collection of code snippets to compare Java and Kotlin.

When we announced Kotlin as a supported language for Android, there was a tremendous amount of excitement among developers. Since then, there has been a steady increase in the number of developers using Kotlin. Today, we’re proud to say nearly 60% of the top 1,000 Android apps contain Kotlin code, with more and more Android developers introducing safer and more concise code using Kotlin.

  Kotlin vs Java: Head to Head

This is the 4th post in a series about migrating to functional programming. This week, I'll first implement the Dijkstra algorithm, then migrate the code to a more functional-friendly design. Dijkstra's algorithm allows to find the shortest path in any graph, weighted or not, directed or not. The only requirement is that weights must be positive.

A developer's guide about how to share code between Android and iOS with Kotlin Multiplatform.
