This is a java programming assignment that I am having trouble getting to loop back up to the add more ingredients prompt. I have tried adding the following code but keep getting "missing return statement" errors. So I have resorted to repeating the whole code twice just to get a couple of ingredients! :

do { System.out.println("Please enter the ingredient name or type 'e' if you are done: ");

String ingredientName = scnr.next();

if (ingredientName.toLowerCase().equals("e")) {

addMoreIngredients = false;

} else {

Ingredient tempIngredient = new Ingredient().enterNewIngredient(ingredientName);

recipeIngredients.add(tempIngredient);

}

} while (addMoreIngredients); ....

CANT GET THIS TO WORK WITH ALL THE OTHER WHILE STATEMENTS USED TO VALIDATE INPUT!

I am also having trouble figuring out how to add the following components: I have added the instance variable accessors, mutators but can't seem to get much further because I can't get the original code to loop back to add more ingredients. Here is the code I was given to build on:

public class SteppingStone6_RecipeBox {

/** * Declare instance variables: * a private ArrayList of the type SteppingStone5_Recipe named listOfRecipes * */

/** * Add accessor and mutator for listOfRecipes * */

/** * Add constructors for the SteppingStone6_RecipeBox() * */

/** * Add the following custom methods: *

* //printAllRecipeDetails(SteppingStone5_Recipe selectedRecipe) * This method should accept a recipe from the listOfRecipes ArrayList * recipeName and use the SteppingStone5_Recipe.printRecipe() method * to print the recipe

* * //printAllRecipeNames() <-- This method should print just the recipe * names of each of the recipes in the listOfRecipes ArrayList * *

//addRecipe(SteppingStone5_Recipe tmpRecipe) <-- This method should use * the SteppingStone5_Recipe.addRecipe() method to add a new * SteppingStone5_Recipe to the listOfRecipes * */

/** * A variation of following menu method should be used as the actual main * once you are ready to submit your final application. For this * submission and for using it to do stand-alone tests, replace the * public void menu() with the standard * public static main(String[] args) * method * */ public void menu() {

// Create a Recipe Box //SteppingStone6_RecipeBox myRecipeBox = new SteppingStone6_RecipeBox();

//Uncomment for main method Scanner menuScnr = new Scanner(System.in);

/** * Print a menu for the user to select one of the three options:

* */ System.out.println("Menu " + "1. Add Recipe " + "2. Print All Recipe Details " + "3. Print All Recipe Names " + " Please select a menu item:");

while (menuScnr.hasNextInt() || menuScnr.hasNextLine()) {

System.out.println("Menu " + "1. Add Recipe " + "2. Print All Recipe Details " + "3. Print All Recipe Names " + " Please select a menu item:");

int input = menuScnr.nextInt();

/** * The code below has two variations: *

2. Code used with the public static main() method * * One of the sections should be commented out depending on the use. */

/** * This could should remain uncommented when using the * SteppingStone6_RecipeBox_tester. *

* Comment out this section when using the * public static main() method */

if (input == 1) { newRecipe(); } else if (input == 2) {

System.out.println("Which recipe? ");

String selectedRecipeName = menuScnr.next();

printAllRecipeDetails(selectedRecipeName);

} else if (input == 3) { for (int j = 0; j < listOfRecipes.size(); j++) {
