Java to Kotlin: A Refactoring Guidebook
What People are Saying
The fastest way to upgrade your skills from Java to Kotlin. Essential reading for any professional Java developer.
Nat and Duncan open the book by saying they wish this book had existed when they adopted Kotlin. I completely agree. The book takes their experiences, their trials and errors, and helps you, the reader, to be on the right path. It definitely is a book that should be on anyone’s shelf coming to Kotlin from the JVM ecosystem. An enjoyable read, and an even better reference guide!
To take familiar good old Java code and see it transform, incrementally, into concise, clear, expressive and easy to maintain Kotlin code is a wonderful way to learn the language. Benefit from the experience McGregor and Pryce have distilled in this book.
