To work effectively with Kotlin, knowing how to initialize a List of lists is important. Also known as a two-dimensional array, or a matrix, a list of lists is a data structure that is defined as a single list where each element is, itself, a list. In this tutorial, we’ll explore...
本文探讨了在 Kotlin 中初始化列表列表的不同方法。 1.使用 List 构造函数 初始化列表列表的标准解决方案是使用 List 或者MutableList 构造函数。如下所示: 1 2 3 4 5 6 fun main() { val M = 3 val listOfLists: MutableList<MutableList<Int>> = MutableList(M) { mutableListOf<Int>() } println(...
Thefill()function will initialize the array in Kotlin with the given value. However, this requires declaring variables to hold the values for size and items to later initialize the array. Output: We need to convert the range to a list with thetoList()function and add the individual values ...
