Here is one way you could do that. I hope this helps get you started with that.

import java.util.ArrayList;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        //Make an ArrayList to hold the random hours
        List<Double> randomHours = new ArrayList<>();
        //Number of employers to determine how many random hours
        int numberOfEmployes = 25;
        for (int i = 0; i < numberOfEmployes;  i++) {
            //Make a random number 1-8
            double random = Math.random() * 8 + 1;
            //check to see if > 8
            if (random > 8) random = 8;
            //add the random number to ArrayList
            //Print random number
            System.out.printf("%.2f%n", random);
