6/29/2023 0 Comments Kotlin any typeHere’s what those examples look like in the REPL: > 1. I couldn’t do that with Java, so I had to settle for less-readable code that looked like this: if (between(x, 1, 10)) ")īecause Any is the root of all Kotlin objects - like in Java - it works on all Kotlin types: 1.printMe() Using the dynamic type basically turns off Kotlin’s type checker. But in order to facilitate interoperability with JavaScript code, Kotlin/JS offers the dynamic type. Statically typed languages are constrained to only support a known set of types. In the years before Kotlin, I wanted an Android method that would let me write code like this: if (x.between(1, 10)). Kotlin is a statically typed programming language. If you’ve used implicit classes in Scala, extension functions are just like those. It’s worth mentioning that Kotlin’s Any is pretty similar to Java’s Object, which means it’s the supertype of all other classes. Extension functions let you add new methods to existing classes (like String, Int, etc.).
