How to Sort a List in Descending Order in Kotlin ?

Answer

To sort a list in descending order in Kotlin, you can use the sortedByDescending method.

✐ Examples

1 Sort a List of Integers in Descending Order

In this example,

We create a list named numbers with integer values.
We use the sortedByDescending method on the numbers list to sort it in descending order.
The sortedByDescending method returns a new list sorted in descending order, leaving the original list unchanged.
Finally, we print the sorted list to the console.

Kotlin Program

fun main() {
    val numbers = listOf(5, 2, 8, 1, 3)
    val sortedNumbers = numbers.sortedByDescending { it }
    println("Sorted list in descending order: $sortedNumbers")
}

Output

Sorted list in descending order: [8, 5, 3, 2, 1]

2 Sort a List of Strings in Descending Order

In this example,

We create a list named words with string values.
We use the sortedByDescending method on the words list to sort it in descending order based on string length.
The sortedByDescending method returns a new list sorted in descending order, leaving the original list unchanged.
Finally, we print the sorted list to the console.

Kotlin Program

fun main() {
    val words = listOf("banana", "apple", "cherry")
    val sortedWords = words.sortedByDescending { it.length }
    println("Sorted list in descending order: $sortedWords")
}

Output

Sorted list in descending order: [banana, cherry, apple]
