![]() ![]() Then we sorted this map by changing it to a list and with the help of. There is no need to use a traditional for loop in Kotlin, because you can using Kotlin lambdas to makes your code more expressive and readable. We inserted couple of values to this map and printed its key-values using a forEach. Like Random is one of the abstract class types, and it is used to generate the pseudo-random number generator it has its own keyword and its syntax for to perform the operations in the code. Here, we have created one hashMap with String as key and Int as the value. In kotlin language has many default classes, methods and keywords for to implement the application. The for-each construct is also applicable to arrays, where it hides the index. forEachIndexed - Kotlin Programming Language Common JVM JS Native Version 1. However, in the code you've written so far, you've mostly worked with data consisting of a single value, like a number or piece of text displayed on the screen. We can understand it using the below code example. Method 1: sort a map by values by converting it to a list: Convert the map to a list. The iterator variable occurs three times in each loop: that is two chances. Introduction In many apps, you've probably seen data displayed as a list: contacts, settings, search results, etc. ![]() If you do not want to use the built-in functions of Kotlin Arrays to find the index of an item in Array, you can use the For Loop to find the index of an element in the array. So that the datas are stored and retrieved using the index format regularly the list and map values are additionally called using the forEach() loop statement. Output Volvo index is: 4 Use For loop to find the index of an item in Array Get the index of an item in integer type values array fun main() ![]()
