2it annoys me when people downvote new users without explaining why. Your question has been downvoted because questions on StackOverflow should be more specific. So you should show what you've tried and why it didn't wok.Paul D'Ambra– Paul D'Ambra2017-12-27 09:59:45 +00:00Commented Dec 27, 2017 at 9:59

To sort the same array we can use
array.sort()
This inbuilt method will sort in alphabetic order. We can also sort Int Array and other array types using inbuilt sort() method
To sort an array without changing the original we can use
val array = arrayOf("abc","bcd","xyz","ghi","acd")
val sorted = array.sortedArray()

It might be interesting to not modify the original array. Therefore sortedArray can be used:
val array = arrayOf("abc","bcd","xyz","ghi","acd")
val sorted = array.sortedArray()
println(array.contentDeepToString())
println(sorted.contentDeepToString())
//[abc, bcd, xyz, ghi, acd]
//[abc, acd, bcd, ghi, xyz]
It creates a new Array without modifying the original.
Otherwise, the original string array can be modified and sorted with sort().
