how to use random on a string code example

Example 1: java random between two strings

public class RandomSelect {

    public static void main (String [] args) {

         String [] arr = {"A", "B", "C", "D"};
         Random random = new Random();

         // randomly selects an index from the arr
         int select = random.nextInt(arr.length); 

         // prints out the value at the randomly selected index
         System.out.println("Random String selected: " + arr[select]); 
    }
