You shall get the something similar to the following printed to the console. In the following example we are iterating though an integer range using for loop. In this tutorial, we will learn how to use For Loop for different kinds of scenarios where we cover a list, a range, a map, etc. You can iterate through array, map or anything that provides an iterator. The implementation and use of For loop is conceptually similar to Java for loop. If items is not changed in the loop, then the maximum number of iterations is items.size. The for loop has run for all the elements in the range one by one. Let's Consider an example, we want to print all the elements in a list The syntax of for loop in Kotlin is different from the one in Java. Here, the loop iterates through the range and prints individual item. It is not possible to change the value of s manually inside the loop. Kotlin’s loops are similar to Python’s. for.

For loops are used to get each and evey elements of the Collection, List. In Kotlin, the for loop works like the forEach in C#. Kotlin For Loop. In this blog, we will talk about the ForEach function in Kotlin. The Kotlin Standard Library also provides numerous useful functions to iteratively work upon collections. With function literals, local functions and object expression, functions can be nested in Kotlin. After every iteration, the value of i is incremented by 1.
