Question

In Java): A vending machine serves chips, fruit, nuts, juice, water, and coffee. The machine owner wants a daily report indicating what items sold that day. Given boolean values (true or false) indicating whether or not at least one of each item was sold (in the order chips, fruit, nuts, juice, water, and coffee), output a list for the owner. If all three snacks were sold, output "All-snacks" instead of individual snacks. Likewise, output "All-drinks" if appropriate. For coding simplicity, output a space after every item, including the last item.
