Write a java program that accepts the ingredients for a recipe in cups and converts to ounces
Tanzania [10]

Answer:

Explanation:

public static int cupsToOunces (int cups) {

   

       int ounces = cups * 8;

       return ounces;

       

   }

This is a very simple Java method that takes in the number of cups in the recipe as a parameter, converts it to ounces, and then returns the number of ounces. It is very simple since 1 cup is equal to 8 ounces, therefore it simply takes the cups and multiplies it by 8 and saves that value in an int variable called ounces.
