Why Kotlin?

Unlike other languages, Kotlin offers a lot of power over Java, while not taking anything away. Let's take a look at the following screenshot to see how:

Kotlin is interoperable with Java. It is possible to write applications containing both Java and Kotlin code, calling one from the other. Calling Java code from Kotlin is simpler, as opposed to the other way around, but the former will be the case most of the times anyway, where new Kotlin code is added on top of legacy Java code. Kotlin is interoperable and can use all the Java libraries and legacy coding without having to do any code conversion. It is possible to inject Kotlin into a Java project without boiling the ocean.
