Project 4: Menu Items
Academic Integrity
Academic integrity means that you submit for a grade work that is entirely yours. The following figures indicate where and who can help:
Objectives:
- Write classes in an inheritance hierarchy
- Implement a polymorphic method
- Create an ArrayList object
- Use ArrayList methods
Assignment
For this project, you get to design and write a Java program to keep track of various menu items. Your program will store, display and modify salads, sandwiches and (you guessed it) frozen yogurts. Present the user with the following menu options:
Actions: 1) Add a salad 2) Add a sandwich 3) Add a frozen yogurt 4) Display an item 5) Display all items 6) Add a topping to an item 9) QuitIf the user does not enter one of these options, then display:
Sorry, <NUMBER> is not a valid option.Where <NUMBER> is the user's input.
All menu items have the following:
- Name (String)
- Price (double)
- Topping (StringBuilder or StringBuffer of comma separated values)
- Side (String)
- Dressing (String)
- Bread type (String)
- Base yogurt flavor (String)
Sorry, could not find <NAME> in the listWhere <NAME> is the user's input. When displaying all of the menu items, display them in the order that they were entered. Note, for adding a topping to a menu item, verify that that the specified item is in the list before requesting the topping.
For this project, you get to have at least a separate class for a salad, sandwich and frozen yogurt. Store each class in a separate file. Furthermore, they need to be organized into an inheritance hierarchy. You are welcome to have more classes if they make sense in the hierarchy. You can use an abstract class if you want to. Note, this project was designed to minimize changes to the code that was in your FrozenYogurt class from Project 3. You will need to submit each of these .java files to codePost and CougarVIEW so that they can be compiled with your other code.
Additionally, have a driver class named Menu. Store all of the menu item objects (i.e., the salad, sandwich and frozen yogurt objects) in a single ArrayList in this class. Create the ArrayList in the main() method of your Menu class. You are not allowed to explicitly use the Object class anywhere in your Menu class (meaning, you should not have "Object" anywhere in your code in Menu.java). Also, do not store String objects in the ArrayList. Lastly, do not use instanceof in any of your .java files.
Only ask for input in your Menu class. Only display output in your Menu class.
codePost does not support the package statement. If your IDE inserted, then please remove that line of code from each class.
Examples
Note, user input is in bold face blue and underlined text is required for test cases.Add 2 Yogurts

Bonuses
- Run your code in a debugger (for example, in BlueJ) and include a screenshot that shows instance variables for your Salad class. For the name of the salad, use your own name.
- Submit your project (.java files to codePost and the rubric to CougarVIEW) at least 24 hours before the due time and earn at least 90% of points.

I, (REPLACE WITH YOUR FULL NAME), affirm that the code that I submitted is my own work and that I did not receive help that was not authorized by the instructor.
Copy and paste this rubric into a rubric-MenuItems.txt file (not a .docx, .doc nor .rtf file). Think of this as a checklist to ensure that you receive the maximum points possible. For each grade item, fill in your estimate for the grade you deserve. Additionally, include your estimate of how many hours your spent. Lastly, replace, "(REPLACE WITH YOUR FULL NAME)" with your full name to indicate that what you are submitting is entirely your own work.
Submission
The submission process has two parts:
- codePost
Submit your Menu class and your 4+ other classes to codePost.io. Note, codePost will only require Menu.java, but you need to also upload the other 4+ .java files otherwise it can not compile and run your code. To register for a free codePost account, please follow these instructions. You can submit to codePost multiple times if you want. Only your last submission will be graded. Watch this short video for a demonstration of submitting an assignment and reviewing the results:
- CougarVIEW
Submit your rubric-MenuItems.txt to the appropriate Assignment tab/folder in CougarVIEW. This is required to receive detailed graded feedback on your project. If you resubmit your rubric, this will effectively replace your previous submission.
Notes
- Start small and iteratively build off of a successful base. For example, get the main loop working. Verify that it's working. Then, work on action 3 and run it. Then, implement action 5 and add in some frozen yogurts and verify that they're in your ArrayList. Now, upload it to codePost and it should pass one of the tests. Get it to pass the first test before moving on. Then, implement action 4 and run it.
- Make sure to look carefully at rounding. Only round the displayed values and not the stored values. Round all money values to 2 decimal places when displaying them.
Help
- Getting Help: This project sometimes takes students many, many hours. Please promise yourself that you will reach out to the CS Tutors or your instructor for help if you have already spent 10 or more hours on the project or if you have been stuck for more than 1 hour.
- Only have one Scanner object in your program.
- If you are looking into what's wrong with you output and codePost is reporting "Log length exceeded error", then let me suggest some options:
- You could temporarily comment out the menu to reduce that amount of output. Do NOT comment out the part that has:
Please choose from the above actions:
because "choose" is required by codePost.
- You could temporarily comment out the menu to reduce that amount of output. Do NOT comment out the part that has:
Challenges (worth 0 points)
- Add in an action 7 that removes a specified item
- Add in an action 8 that sorts the items
- Instead of using a StringBuilder or StringBuffer to store the toppings, use an ArrayList. Furthermore, do not add in an additional topping if it already exists in the list.
