One of Kotlin’s strengths is that generally speaking, the code you might write in Java is generally more compact in Kotlin without losing any of the readability, functionality, or performance.
An odd case where that doesn’t prove to be true is declaring loggers as Java developers.
This year at JVMLS, Brian Goetz talked about Pattern Matching on the JVM and how it might be modeled. In particular he spoke about:
Today’s Kotlin library article is about the kotlin.concurrent package, and everything that adds to the platform.
Java’s concurrency package is already quite sophisticated, and rather than re-invent so many extremely delicate abstractions, the Kotlin authors focused on making the libraries better suited to the language by decorating and shortening various features.
This is the second article in a series around Kotlin standard library additions. This article is all about the Kotlin comparator factory functions.
This is the first in a series of articles that will quickly go over some of the more interesting bits of the Kotlin standard libraries for Java. Today’s run-through is about some of the more interesting affordances for I/O based programming.
