Java Interoperability
Last updated
What is Java Interoperability?
Kotlin is 100% interoperable with the Java programming language, and major emphasis has been placed on making sure that your existing codebase can interact properly with Kotlin. You can easily call Kotlin code from Java and Java code from Kotlin. This makes adoption much easier and lower-risk. There's also an automated Java-to-Kotlin converter built into the IDE that simplifies migration of existing code.
