Expected Release: Fall 2025

Covers the Kotlin Standard Library as well as the Java Standard Library from the perspective of Kotlin, favoring the idiomatic Kotlin approach where there is an overlap. This will be by far our longest cheat sheet to date, estimated to be 18 pages, covering Scope Functions, Comparator, Comparable, Collection Utilities, Format, Strings, Regular Expressions, Date and Time (java.time), DateTimeFormatter, kotlin.time, Math, NIO Path, Internationalization, and more.

Note: Coming Soon titles are subject to change without notice. Please consider the product description when the cheat sheet is published.
