![]() ![]() The start and stop are inclusive in the Range and the value of step is by default 1. I came up with these general functions: fun forloop(state: S, condition: (s: S) -> Boolean, postExecution: (s: S) -> Unit, block: (s: S) -> Unit) ")Īlthough, in compliance with the language philosophy, you should only use this in rare circumstances. The range in Kotlin consists of a start, a stop, and the step. For example, a range, array, string, etc. The for loop in Kotlin can be used to iterate through anything that provides an iterator. In Kotlin, the for loop works like the forEach in C. For integer numbers, there are four types with different sizes and, hence, value ranges: When you initialize a variable with no explicit type specification, the compiler automatically infers the type with the smallest range enough to represent the value. Generally, the for loop is used to iterate through the given block of code for the specified number of times. ![]() However, I needed a traditional for loop (like java) with an immediately terminating state scope, exit condition that evaluates before loop-body execution, and a post-execution operation (my use case was complicated: I needed to repeat using a dynamic exit condition based on a compression routine and powers of 2). Kotlin provides a set of built-in types that represent numbers. ![]() Kotlin is trying to enforce fluent iteration, which covers the vast majority of looping constructs. ![]()
