How to Sort an Array in Ascending Order in Kotlin ?

Answer

To sort an array in ascending order in Kotlin, you can use the built-in sorting functions like `sorted()` or `sort()` depending on whether you want a new sorted array or to sort the array in-place.

✐ Examples

1 Sort Array of Integers

In this example,

Create an array of integers, for example, numbers.
Use the sorted() function to obtain a new sorted array.
The sorted array will be in ascending order.
Print the sorted array to see the result.

Kotlin Program

fun main() {
    val numbers = arrayOf(5, 2, 8, 1, 9)
    val sortedNumbers = numbers.sorted()
    println("Sorted Array of Integers: ${sortedNumbers.joinToString()}")
}

Output

Sorted Array of Integers: 1, 2, 5, 8, 9

2 Sort Array of Strings

In this example,

Create an array of strings, for example, words.
Use the sorted() function to obtain a new sorted array.
The sorted array will be in ascending order based on string comparison.
Print the sorted array to see the result.

Kotlin Program

fun main() {
    val words = arrayOf("apple", "banana", "cherry", "date")
    val sortedWords = words.sorted()
    println("Sorted Array of Strings: ${sortedWords.joinToString()}")
}

Output

Sorted Array of Strings: apple, banana, cherry, date
