6/7/2023 0 Comments Kotlin for each loopIt 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. We can also use the for-each loop to iterate through the elements of an array. However, thanks to the step keyword, we have skipped one item each time to. How do I iterate two lists in Kotlin I want to assign each value in one list to the equivalent textview in another list, like 1 : 1 assignment. Here, we are using the length property of the array to get the size of the array. In these two examples, we have iterated over a range of 10 items. Notice the expression inside the loop, age.length. 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 In the above example, we are using the for Loop in Java to iterate through each element of the array. Now, in Kotlin we can perform the same operation using ForEach If you are familiar with Java or C, this is equivalent to the foreach loops found in those. So, if we want to print all the item in the list using for loop, we will use In Kotlin, all for loops rely on iteration to do their work. 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. You will learn more about ranges in the next chapter - which will create a range of values. In Kotlin, the for loop is used to loop through arrays, ranges, and other things that contains a countable number of values. In this blog, we will talk about the ForEach function in Kotlin. Unlike Java and other programming languages, there is no traditional for loop in Kotlin. We can also use while loops.įor loops are used to get each and evey elements of the Collection, List. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. 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. A tag already exists with the provided branch name.
