import java.util.ArrayList;
import java.util.Random;

public class Loop {
    public static void main(String[] args) {
        // Create ArrayList and Random
        ArrayList<String> list = new ArrayList<String>();
        Random rand = new Random();

        // Add values to ArrayList list
        list.add("hi");
        list.add("World");
        list.add("Greetings");
        list.add("Jupiter");
        list.add("Riddle");

        // Loop 5 times
        for(int i=0;i<5;i++) {
            // Randomly select a number based on the number of iterations the loop has run through
            int n = rand.nextInt(5-i);
            // Print that index to console and remove from the ArrayList list
            System.out.println(list.get(n));
            list.remove(n);
        }
    }
