Answer 1

The correct way of using this is:

Make two class one for the ingredients information and one for print the info or can use in one class also.

Ingredient.java:

public class Ingredient {

   private String nameOfIngredient = "";

   private int numberCups = 0;

   private int numberCaloriesPerCup = 0;

   public Ingredient(String nameOfIngredient, int numberCups, int numberCaloriesPerCup) {

       this.nameOfIngredient = nameOfIngredient;

       this.numberCups = numberCups;

       this.numberCaloriesPerCup = numberCaloriesPerCup;

   }

   public String getNameOfIngredient() {

       return nameOfIngredient;

   }

   public int getNumberCups() {

       return numberCups;

   }

   public int getNumberCaloriesPerCup() {

       return numberCaloriesPerCup;

   }

   public double getTotalCalories() {

       return numberCaloriesPerCup * numberCups;

   }

   @Override

   public String toString() {

       return numberCups + " cups of " + nameOfIngredient + ", total Calories: " + getTotalCalories();

   }

}

SteppingStone2_IngredientCalculator.java:

public class SteppingStone2_IngredientCalculator {
   public static void main(String[] args) {
       Ingredient ing = new Ingredient("Apple", 10, 20);
       System.out.println(ing.toString());
   }
}

sample output:

10 cups of Apple, total Calories: 200.0
