Question

At a coffee shop, a coffee costs $1. Each coffee you purchase, earns one star. Seven stars earns a free coffee. In turn, that free coffee earns another star. Ask the user how many dollars they will spend, then output the number of coffees that will be given and output the number of stars remaining.

Answer 1

import java.util.Scanner;

public class Q {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.println("Dollars:");
        int dollars = in.nextInt();
        int coffees = dollars;
        int stars = dollars;
        while (stars >= 7) {
            coffees += stars / 7;
            stars = (stars % 7) + (stars / 7);

        }
        System.out.println("Coffees: " + coffees);
        System.out.println("Stars: " + stars);
    }
}
