    Hello please help with creating a user-defined method with control structure that calculates the cost of the recipe. I also need a test file to provide sample output. Any assistance would be greatly appreciated.

    // create new recipe object and return it.
     
    return new Recipe1(recipeName, numServings, ingredients, totalCalories);
     
    }
     
    }

    and this for a different test file

     
    package steppingstonesTesting;
     
    /*

    import  java.util.Arrays;
     
    public class RecipeTest {
     
    public static void main(String[] args) {
     
    // create one hardcoded recipe.
     
    String[] ingredients = {"Rice", "Chicken", "Chilli", "Onion", "Tomato", "Masala", "Ginger", "Garlic"};
     
    Recipe1 masalachickenRecipe = new Recipe1("Chicken Masala", 2, Arrays.asList(ingredients), 1400);
     
    masalachickenRecipe.printRecipe();
     
    // create a new recipe by taking input from the user.
     
    Recipe1 createdRecipe = Recipe1.createNewRecipe();
     
    createdRecipe.printRecipe();
     
        }
     
    }

    Default Re: Need assistance with creating CONTROL STRUCTURE for a recipe program

    Please fix the indentations of the posted code. Code without indentations is hard to read and understand.

    creating a user-defined method with control structure that calculates the cost of the recipe.
    Can you describe in more detail what the method is supposed to do?
    What class is the method supposed to be in?
    What arguments should the method take?
    What should the method return?
    If you don't understand my answer, don't ignore it, ask a question.
