Sorts the array in-place according to the natural order of its elements.
The sort is stable. It means that equal elements preserve their order relative to each other after sorting.
import kotlin.test.*
fun main(args: Array<String>) {
//sampleStart
class Person(val firstName: String, val lastName: String) : Comparable<Person> {
override fun compareTo(other: Person): Int = this.lastName.compareTo(other.lastName)
override fun toString(): String = "$firstName $lastName"
}
val people = arrayOf(
Person("Ragnar", "Lodbrok"),
Person("Bjorn", "Ironside"),
Person("Sweyn", "Forkbeard")
)
// before sorting
println(people.joinToString()) // Ragnar Lodbrok, Bjorn Ironside, Sweyn Forkbeard
people.sort()
// after sorting
println(people.joinToString()) // Sweyn Forkbeard, Bjorn Ironside, Ragnar Lodbrok
//sampleEnd
}

fromIndex
- the start of the range (inclusive) to sort, 0 by default.
toIndex
- the end of the range (exclusive) to sort, size of this array by default.
IndexOutOfBoundsException
- if fromIndex is less than zero or toIndex is greater than the size of this array.
IllegalArgumentException
- if fromIndex is greater than toIndex.
