1. Random string from array of strings

We need to generate random index of an array.
As nextInt function is called we pass int bound to have results within array size.

import java.util.concurrent.ThreadLocalRandom;

public class JavaRandomStringFromArray {
    
    public static String randomStringFromArr() {
        String[] arr = {"A", "B", "C", "D", "E", "F"};
        int randIdx = ThreadLocalRandom.current().nextInt(arr.length);
        String randomElem = arr[randIdx];
        return randomElem;
    }

    public static void main(String[] args) {
        System.out.println(randomStringFromArr()); // F
        System.out.println(randomStringFromArr()); // B
        System.out.println(randomStringFromArr()); // A
    }
}
