Question

1. Write a class that represents a Recipe as shown in the UML diagram below. Recipe -name: string -cookTime: int -prepTime: int - ingredients: ArrayList<String> +Recipe(String name, int cTime, int pTime, String... ingredients) +Recipe(String name, int cTime, int pTime) +getNumberOfIngredients(): int +addIngredient(String ingredient): void +getName(): String +getTotalRecipeTime(): int +get Ingredient(int index): String +remove Ingredient(String ingredient): String

import java.util.ArrayList; public class Recipe { private String name; private int cookTime; private int perpTime; private ArrayList<String> ingredients; public Recipe(String name, int cookTime, int perpTime, ArrayList<String> ingredients) { this.name = name; this.cookTime = cookTime; this.perpTime = perpTime; this.ingredients = ingredients; } public Recipe(String name, int cookTime, int perpTime) { this.name = name; this.cookTime cookTime; this.perpTime = perpTime; ingredients = new ArrayList<String>(); } int getNumberOfIngredients(){ return ingredients.size(); } void addIngredient(String ingredient){ ingredients.add(ingredient); }

String getName() { return this.name; } int getTotalRecipeTime() { return this.cookTime+this.perpTime; } String getIngredient(int index) { if(index<o||index>-ingredients.size(){ return "Not valid"; } return ingredients.get(index); } String removeIngredient(String ingredient){ if(ingredients.remove(ingredient)){ return "Successful"; }else{ return "Error"; } } }

import java.util.ArrayList; public class Recipe { private String name; private int cookTime; private int perpTime; private ArrayList<String> ingredients; public Recipe(String name, int cookTime, int perpTime, ArrayList<String> ingredients) { this.name = name; this.cookTime = cookTime; this.perpTime = perpTime; this.ingredients = ingredients; } public Recipe(String name, int cookTime, int perpTime) { this.name = name; this.cookTime = cookTime; this.perpTime = perpTime; ingredients = new ArrayList<String>(); } int getNumberOfIngredients(){ return ingredients.size(); } void addIngredient(String ingredient){ ingredients.add(ingredient); } String getName(){ return this.name; } int getTotalRecipeTime(){ return this.cookTime+this.perpTime; } String getIngredient(int index){ if(index<0||index>=ingredients.size()){ return "Not valid"; } return ingredients.get(index); } String removeIngredient(String ingredient){ if(ingredients.remove(ingredient)){ return "Successful"; }else{ return "Error"; } } }
