If kotlin provides enough benefit that your technical stake holders agree it’s the way to go over Java, doing the migration incrementally will dramatically improve odds of a successful transition because you won’t be holding up delivery of business value for benefits that aren’t visible to the end users of your software.

Everything just seems to make sense, and the interoperability with Java is great. In this lesson, youll learn how to create your first Kotlin file with IntelliJ.Watch the entire FREE Kotlin Programming course here: In this lesson, youll learn. I had only worked with Kotlin for a few hours before writing this tutorial,īut I’m already a very big fan of the language. Import .AtomicInteger class UserDao Conclusion
