How to Shuffle an Array in Kotlin ?

Answer

To shuffle an array in Kotlin, you can use the shuffle method from the kotlin.collections package.

✐ Examples

1 Shuffle an Array of Integers

In this example,

We create an array of integers named arr with the values 1, 2, 3, 4, and 5.
We convert the array to a mutable list using the toMutableList method, which allows us to use the shuffle method.
We call the shuffle method on the mutable list to randomly shuffle the elements.
Finally, we print the shuffled array to standard output.

Kotlin Program

fun main() {
    val arr = arrayOf(1, 2, 3, 4, 5)
    val shuffledArr = arr.toMutableList().apply { shuffle() }
    println("Shuffled array: $shuffledArr")
}

Output

Shuffled array: [3, 1, 5, 2, 4]

2 Shuffle an Array of Strings

In this example,

We create an array of strings named arr with the values "apple", "banana", "cherry", "date", and "elderberry".
We convert the array to a mutable list using the toMutableList method, which allows us to use the shuffle method.
We call the shuffle method on the mutable list to randomly shuffle the elements.
Finally, we print the shuffled array to standard output.

Kotlin Program

fun main() {
    val arr = arrayOf("apple", "banana", "cherry", "date", "elderberry")
    val shuffledArr = arr.toMutableList().apply { shuffle() }
    println("Shuffled array: $shuffledArr")
}

Output

Shuffled array: [cherry, apple, elderberry, banana, date]
