how to initialize mutable list kotlin
To initialize a mutable list in Kotlin, you can follow these steps:
Step 1: Declare a variable to hold the mutable list. You can use the var
keyword to declare a mutable variable.
Step 2: Use the mutableListOf()
function to create an empty mutable list. This function creates and returns a new MutableList
object.
Step 3: Assign the result of the mutableListOf()
function to the variable declared in step 1. This will initialize the mutable list with an empty state.
Here is an example of how you can initialize a mutable list in Kotlin:
var myList: MutableList<Int> = mutableListOf()
In this example, we declare a mutable list variable called myList
of type MutableList<Int>
. We initialize it with an empty state using the mutableListOf()
function.
You can replace Int
with any other data type you want to store in the mutable list. This allows you to create a mutable list of any type, such as String
, Double
, or custom data classes.
