What does this code do?

Since learning Scala and Kotlin, I've been wondering why much of the code written in Kotlin and Scala has been easier to read than its respective Java equivalent.

Even with implicits, Scala code seems to flow in a much more fluid manner. More like a novel rather than a technical specification.

Kotlin and Scala (particularly Scala) usually have more complicated constructs and intricacies than the Java equivalent. There's no denying some features in either language can be strainous to understand. Scala and Kotlin are complex languages and harder to learn than Java. More complex code can be written with them. Languages within languages can be written. There are multiple ways to accomplish the exact same task.

But don't we have the same expressiveness with English. One of the most complicated languages in the world. The magnitudes of expressiveness that English contains are mind boggling. Yet I haven't seen many native speakers complaining about the actual language. They only seem to complain about the speakers/writers of the language.

What does this Java code do? The answer is nothing. And it doesn't even fit on a page.
