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()));

Simple Kotlin Solution

myList.random()

random() is a default extension function included in base Kotlin on the Collection object.
