Create a class named RecipeFactory

public static Recipe makeRecipe(String recipeType, String recipeName, HashMap ingredients)

public static final String (DESSERT and DINNER)

Dessert and Dinner

Create an abstract class named Recipe

protected HashMap ingredients

Key: ingredient name

Value: ingredient amount

protected String name

HashMap getIngredients()

Can implement here

String getName()

Can implement here

Extend your abstract class in DessertRecipe and DinnerRecipe

Override toString

Expected output on next slide

Use the StringBuilder class

Implement a constructor that takes String name and HashMap ingredients.

Warning: assigning HashMap from constructor and memory

new HashMap(hashMap)

Hint: use to add a newline and \t to add the tab

Since this will go through an autograder, you must exactly match the formatting (do not add an extra to the very end)

Create a singleton class named Cookbook

private Cookbook() { }

private ArrayList recipes

void addRecipe(Recipe r)

void clearRecipes()

ArrayList getRecipes()

Cookbook getInstance()

Create a file named FinalProject.java

This file will contain all your code when you submit your completed project

Both methods you work on this week should be in the public FinalProjectclass

You can add main to this class to help you test your code

Define a static method that can take a recipe string and convert it into the appropriate Recipe subclass object

Remember:

Key: ingredient name

Value: ingredient amount

Use your RecipeFactory to create the object

Practice with this test string and verify your method works.

String test = "Cake~Dessert~flour@3/4 cups#milk@3/4 cups#sugar@2/3 cups#vanilla@1 tsp";

Define a static method called connectToServer that takes as input a String ipAddress and integer port.

Create a socket (client) and connect to the input port

This will be your connection to the RecipeServer

Make sure your socket is continually reading in messages from the socket

Pseudocode: while (input from socket != null) print out input from socket

Use an InputStreamReader wrapped in a BufferedReader

If you run the following code from main in FinalProject.java

FinalProject.connectToServer(8765);

System.out.println(Hello);

Hello will never be printed

Why?

Update your connectToServermethod

Instead of performing the connection and reading on the main thread, perform the work in a new thread.

To test your changes, run your code from the previous slide. Hello should be print out immediately.

Also make sure you are still able to receive messages continually from RecipeServer.

Write the following methods in your FinalProject class.

public static void serializeRecipe(Recipe r, String path)

Serialize the given recipe to the path

You should only store the following fields

name

ingredients

You can serialize the object as a Recipe

No need to check which child class was input

public static Recipe deserializeRecipe(String path)

Deserialize a Recipe at the given path

Cast the returned object to Recipe

Note: Even if you treat it as a Recipe, the data from the child class you used will be saved

i.e. no need to cast it to the child class

Place all your classes in your FinalProject.java file.

Test to make sure all the code still works.

Submit it online to the autograder.

Here is how testing will be done:

A server socket will await your connection

Recipe strings will be sent over the socket

Your Cookbook should be updated after each recipe

All of your methods will be tested, including your RecipeFactory and Cookbook methods.

Feel free to choose you own recipe names and ingredients.

As you receive recipes over the socket, you should create the appropriate Recipe object (using the factory) and add them to the Cookbook list.

Test your code with the RecipeServercode. You can use 8765 as your testing port.

Note: You will have to run the server and your code separately. You will need to test it locally.

You should be able to continually send messages from the server and receive them from your client.

Do not change the server code this version will be used to test your program.
