Kotlin interoperates with Java and its libraries, and is included with JetBrains' IntelliJ IDEA integrated development environment and Android Studio.

That’s important because if you want to target Android O, create an Instant App, start developing with Kotlin, or use the latest Android app performance tools, you’ll need Android Studio 3.0.

Kotlin is a super new programming language built by JetBrains, which also coincidentally develops the JetBrains IDE that Android Studio — Google’s official developer tool — is based on.
