The for-in loop is used to iterate over a sequence of items contained in a collection or number range. Report this ad The Kotlin for-in Statement
This chapter is intended to provide an introductory overview of both types of flow control in Kotlin. Flow control typically falls into the categories of looping control (how often code is executed) and conditional flow control (whether or not code is executed). Java equivalent code only jumps over single. This is often referred to as flow control since it controls the flow of program execution. How can I modify the loop variable in Kotlin For my particular case, I have a for-loop in. As you can see, Kotlin expects to exit the loop right after index childrenCount condition gets reached. Such decisions define which code gets executed, how many times it is executed and, conversely, which code gets by-passed when the program is executing. Regardless of the programming language used, application development is largely an exercise in applying logic, and much of the art of programming involves writing code that makes decisions based on one or more criteria.

The for loop is used to iterate over any Kotlin object which can be iterated. The for loop in Kotlin is similar to forEach loop in Java.
There is no traditional for loop in Kotlin unlike C, C++, Java etc., which will execute until a condition returns false. In this tutorial, we will discuss about for loop in Kotlin. In Kotlin, for loop is used to iterate through the following because all of them provides iterator.
