![]() Mutable lists provide a lot more functions: get(), set(), plus, minus(), etc. indices ) // You can also use listOrArray to access the element at the given index. The below code works for both lists and arrays for ( i in listOrArray. Here are examples to declare a type-safe mutable lists with various examples: MutableListOf() allows us to manually define type-safe lists. ![]() If you pass in multiple data types in the constructor, the list will automatically be of type Any. To explicitly allow for it, use mutableListOf() to add mixed data types to the list. ![]() Note: Unlike arrayOf(), once mutableListOf() automatically infers a single data type, you can’t change the data type of the list. Using them, we can add, remove, or modify the elements in the list without re-creating it! It works similar to arrayOf(), but provides us functions to perform actions on the list. 1D arrays with dynamic sizeįor lists of dynamic size, we use the function mutableListOf(). Kotlin standard library supports for functions like intArrayOf(), doubleArrayOf(), booleanArrayOf(), etc. It is pretty useful if you want to store data that is strongly typed. Type mismatch: inferred type is String but Int was expected The following example demonstrates how you can create a dynamic array list and initialize the same.Val array = arrayOf ( 10, 20, 30, "40" ) /* Example: Initialize an empty array in Kotlin If a number is provided as the argument, then it will return an arrayList with the given elements. The function definition of arrayList goes like this − fun arrayListOf(): ArrayList An ArrayList is an ordered sequence of elements, however, unlike simple arrays, an ArrayList can contain data of multiple data types. ![]() It would be a dynamic array which means it will automatically expand as we add data into it. Kotlin ArrayList class can be used in order to create an empty arrayList. ![]()
