Hello,

The following JAVA Recipe Box class needs a method to access the custom method I created in the Recipe Items class. Honestly I do not understand what exactly I am doing wrong because, the Recipe Box does not run as expected. Box classes are included. Please help and include explanation.

Thank you.

package recipemanager;

import java.io.PrintStream; import java.util.ArrayList; import java.util.Scanner;

public class RecipeBox { private static ArrayList listOfRecipes = new ArrayList<>(); private static PrintStream PrintStream;

/** * * @return */ public ArrayList getListOfRecipes() { return listOfRecipes; }

public void setListOfRecipes(ArrayList listOfRecipes) { RecipeBox.listOfRecipes = listOfRecipes;//INFO NEXT REVIEW }

public void Recipe() { this.listOfRecipes = new ArrayList<>(); }

public void RecipeBox(ArrayList listOfRecipes) { this.listOfRecipes = listOfRecipes; }

public void printAllRecipeDetails() { RecipeItems tmpRecipe = new RecipeItems();

int i = 0;

for (i = 0; i < listOfRecipes.size(); i++) { tmpRecipe.printRecipe(); } }

public void printAllRecipeNames() {

int i = 0;

for (i = 0; i < listOfRecipes.size(); i++) {

System.out.println(listOfRecipes.get(i)); } }

public void addNewRecipe() {

RecipeItems tmpRecipe2 = new RecipeItems();

listOfRecipes.add(tmpRecipe2.addNewRecipe()); }

public void deleteRecipe(){ Scanner deleteScnr = new Scanner(System.in); String recipeToremove = deleteScnr.next(); for (int h = 0; h < listOfRecipes.size(); h++){ if (listOfRecipes.get(h).recipeName.equals(recipeToremove)){ listOfRecipes.remove(h); break; } } } public static void main(String[] args) { // Create Recipe Box RecipeBox myRecipeBox = new RecipeBox(); Scanner menuScnr = new Scanner(System.in);

System.out.println("Menu " + "1. Add Recipe " + "2. Print All Recipe Details " + "3. Print All Recipe Names " + "4. Remove Recipe " + " Please select a menu item:");

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

int input = menuScnr.nextInt();

if (input == 1) {

myRecipeBox.newRecipe();

} else if (input == 2) {

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

String selectedRecipeName = menuScnr.next();

RecipeItems selectedRecipe = new RecipeItems();

selectedRecipe.setRecipeName(selectedRecipeName);

myRecipeBox.printAllRecipeDetails(selectedRecipe);

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

System.out.println((j + 1) + ":" + myRecipeBox.listOfRecipes.get(j).getRecipeName()); } } else if (input ==4){ myRecipeBox.deleteRecipe(); }

else {

System.out.println(" Menu " + "1. Add Recipe " + "2. Print Recipe " + "3. Adjust Recipe Servings " + "4. Remove Recipe " + " Please select a menu item:"); }

System.out.println("Menu " + "1. Add Recipe " + "2. Print All Recipe Details " + "3. Print All Recipe Names " + "4. Remove Recipe " + " Please select a menu item:"); }

}

}

OUTPUT:

WHEN RUN THE CODE TROWS AN EXCEPTION... IF THE USER ENTER OPTION 1 NOTHING HAPPENS... I GUESS THE ADDNEWRECIPE SHOULD BE INCLUDED IN THE RecipeItems class but I do not understand where or why...

SECOND CLASS:
