It is like an Function approach towards the traditional for-loop way.īoth For loops and ForEach are same when generating output from an array or listįorEach can be more useful if we use it more functional operators. This will also print the same output like before,Īs you can see that using forEach inplace to for loop make the code more concise and smart.įorEach are used to perfrom action on each and every elements of list Now, in Kotlin we can perform the same operation using ForEach So, if we want to print all the item in the list using for loop, we will use Let's Consider an example, we want to print all the elements in a list But before that let's understand how for loop works. In this blog, we will talk about the ForEach function in Kotlin. We can also use while loops.įor loops are used to get each and evey elements of the Collection, List. The syntax of for loop in Kotlin is: for (. Have you ever have iterated through a list or an array in Kotlin or in any programming language ? For loops are traditionally used to do this type of jobs. In Kotlin, for loop is used to iterate through ranges, arrays, maps and so on (anything that provides an iterator).
