![]() It returns the index of an element which will be returned by a subsequent call to the next () function. A simple solution is to use the nextIndex () function from the iterator returned by the ListIterator. The JavaScript forEach method is one of the several ways to loop through. ![]() In Kotlin, listOf() is used to create a list and we can pass different data types at the same time. This article explores different ways to traverse a list with the index in Kotlin. forEach (function(currentValue, index, arr)) Here, function (currentValue. ![]() ![]() In the first example, we show how we can initialize arrays in Kotlin. Kotlin arrays are created with functions such as arrayOf or intArrayOf, or with classes such as IntArray or FloatArray. Each element can be referred to by an index. forEachIndexed - Kotlin Programming Language JVM JS Native Version 1. In the following example, we will be using the same array and we will be using withIndex () to print its values and index. We will use a for loop to iterate over each letter in the string and check for the. withIndex () is a library function of Kotlin using which you can access both the index and the corresponding values of an array. ![]() You can traverse through collection (list, map, set) using the for loop. The syntax of this operator is similar to that of obtaining a value from an array in Java. Kotlin for loop iterating though array indices We can also use array indexes to iterate though the array. The array items are called elements of the array. Else set flag Start to next substring start from i+1th index. Iterate through collection using for loopĪ collection usually contains a number of objects of the same type and these objects in the collection are called elements or items. The syntax of for loop in Kotlin is: for (item in collection) ")*/ ![]()
