Kotlin

One of the rising stars in the software development sky, Kotlin is a cross-platform, general-purpose programming language that’s Google’s preferred language for Android development. That certainly has boosted its popularity but its benefits have also played an important part. Kotlin is like a more concise version of Java, is highly interoperable with it, has many features, is easy to learn, and is less error-prone. 

Kotlin () is a cross-platform, statically typed, general-purpose programming language with type inference. Kotlin is designed to interoperate fully with Java, and the JVM version of Kotlin's standard library depends on the Java Class Library, but type inference allows its syntax to be more concise.
