For loops are traditionally used to do this type of jobs. We can also use while loops. For loops are used to get each and evey elements of the Collection, List. In this blog, we will talk about the ForEach function in Kotlin. But before that let's understand how for loop works. Let's Consider an example, we want to print all the elements in a list

Now, by using break with a label ( break@test in this case), you can break the specific loop. Add a comment. |. 20. Alternatively, you can use the withIndex library function: for ( (index, value) in array.withIndex ()) { println ("the element at $index is $value") } Control Flow: if, when, for, while: https://kotlinlang.org/docs/reference/control-flow.html.

For loop is used to execute the same set of statements, again and again. There is not traditional for loop is in Kotlin that means No initialization or condition increment/decrement. To replace the traditional for loop kotlin uses ranges, in operator, iterators(for collections).

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 Kotlin For Loop Loops can execute a block of code multiple times as long as the loop condition is true.
