Kotlin allows you to write highly expressive, understandable and safe code -- while being 100% interoperable with Java. You can use any Java classes and methods from Kotlin and the other way around. Kotlin improves your Android app code by writing null-safe, concise, and readable code using higher-order extension functions thus, speeds up your development workflow.
