How to Sort a String Array in Dictionary Order in Kotlin - Step by Step Examples
How to Sort a String Array in Dictionary Order in Kotlin ?
Answer
To sort a string array in Kotlin in dictionary order, you can use the `sorted()` function. To sort in descending order, you can use the `sortedDescending()` function.
✐ Examples
1 Sort String Array Ascending
In this example,
- We create a string array `words` with unsorted elements.
- We use the `sorted()` function to sort the array in ascending dictionary order.
- We print the sorted array.
Kotlin Program
fun main() {
val words = arrayOf("banana", "apple", "orange", "grape")
val sortedWords = words.sorted()
println("Sorted Array Ascending: ${sortedWords.joinToString()}")
}
Output
Sorted Array Ascending: apple, banana, grape, orange
2 Sort String Array Descending
In this example,
- We create a string array `words` with unsorted elements.
- We use the `sortedDescending()` function to sort the array in descending dictionary order.
- We print the sorted array.
Kotlin Program
fun main() {
val words = arrayOf("banana", "apple", "orange", "grape")
val sortedWords = words.sortedDescending()
println("Sorted Array Descending: ${sortedWords.joinToString()}")
}
Output
Sorted Array Descending: orange, grape, banana, apple
