Using the Java and Kotlin APIs

Abstract

Kotlin has a language kernel that handles classes, objects, properties, functions, structural constructs, and all that stuff. We’ve been talking about these a lot to this point. Once in a while we have mentioned and used the term Kotlin standard library without explicitly stating what that actually is. In real life a library is a place where much information is available. Whenever you need to know something you can go there and try to find a book that can show you what things are or how they work, or what you have to do to achieve something. For a computer language, a library is something similar: a place with lots of classes and functions that you can use for certain tasks. We already talked about collections, which are governed by library classes and functions.
