I have a String
array:
String [] array={"1","2","3","4","5","6","7","8","9"};
Which I convert into an array list:
ArrayList<String> al = new ArrayList<String>(Arrays.asList(array));
I want to get a random value from my ArrayList.

Use Random
class to do that, argument of method nextInt
is the bound on the random number to be returned. It must be positive:
Random random = new Random();
yourList.get(random.nextInt(yourList.size()));
myList.random()
random()
is a default extension function included in base Kotlin on the Collection
object.
