Kotlin for each loop5/21/2023 ![]() I hope the above gives a bit of an insight into different ways of looping in Kotlin. This shouldn’t matter much in terms of performance, but it’s something to be aware of in performance critical code. In a nutshell, the Kotlin compiler creates an Iterable object and IntRange object, and then the iteration will take place. While the Kotlin forEach on a range looks pretty similar to the other options, under the hood things work a bit different, which can be seen in the linked video at the 25-minute mark. ![]() As such, the syntax of for loop in Kotlin is: for (element in collection) Kotlin loop using a forEach I argue that this loop should iterate over a new line each time (the line below). After that, it ought to exit the loop and move to the first one. I need to divide each integer in a table by the last one in each column, iterating through each column only when the condition is satisfied. Any class which provides an iterator can be looped over. VBA Do While Loop does not want to looping. ![]() In Kotlin the for loop is used to iterate through a diversity of types to loop over, such as collections, ranges and maps. Inspired by the Kotlin Under the Hood: Understand the Internals (Google I/O’19) video (which is a really good video btw, I’d recommend watching it if you haven’t), I wanted to list a few ways of looping it Kotlin. Kotlin provides its own way of looping on ranges. IntStream.range(0, 100).forEach(System.out::println) A Kotlin Approach ![]() Examples of either can be seen below: // Traditional for loop to use various higher-order functions with the List collection, including forEach(). A more modern approach would be something like using a Java 8 IntStream. In the Use function types and lambda expressions in Kotlin codelab. One of the most well-known ways to iterate on a range is to use the traditional for loop. Kotlin For Loop is used to Execute a block of statements that have to be executed repeatedly until a condition evaluates to true Execute a block of statements for each item of a list Execute a block of statements for each point in a range In this tutorial, we will learn different variations of Kotlin For Loop with examples. There’s a common way in Java to do loops.
