Please help me with this project. In project one, we created five classes(BikePart.java, Inventory.java, wareHouse.java, processCommand.java, and main.java). I am going to put all the five classes here to give more inforemation about this project. Based on the five classes, I need to have another class(wareHouseFactory) which has an ArrayList. I also need to have an view(FXML) and controller class. Please provide the solution for the controller calss as well. The following is an example of test cases for the sell command.

Setup Prior to Running the Test Case

Program is running with a main warehouse and two sales vans: van1 and van2 .

The van1 sales van has 10 saddle bike parts: saddle,12345678905,50.00,40.00,true

The van2 sales van does not have any saddle bike parts.

The van2 sales van has 5 wheel bike parts: wheel,12345678910,100.00,85.00,false

Test 1: Sell saddle from van1 sales van, saddle is on sale

Inputs

name of product to sell - saddle, name of sales van from which to sell - van1

Expected Results

Display shows saddle, cost is 40.00 (sales price), and current date

The number of saddles in gusty sales van is now 9

Test 2: Sell saddle from van2 sales van, saddle is not on van

Inputs

name of product to sell - saddle, name of sales van from which to sell - van2

Expected Results

Part not found

Test 1: Sell wheel from van2 sales van, wheel is not on sale

Inputs

name of product to sell - wheel, name of sales van from which to sell - van2

Expected Results

Display shows wheel, cost is 100.00 (regular price), and current date

The number of wheels in van2 sales van is now 4

Introduction for this project:

Introduction

You are a programmer working for Bicycle Parts Distributorship. BPD has a warehouse full of

bicycle parts. The warehouse parts and database are as described in Project 1. In this increment

of the project BPD has purchased vans and hired sales personnel who drive the vans. The sales

personnel load their vans with bicycle parts, which they sell to bicycle shops located throughout

the sales district. Each sales van is its own warehouse that has inventory. When a sales van is

loaded with parts, the inventory in the main warehouse is decremented and the inventory in the

sales van is incremented. Sometimes, a sales associate does not want to drive to the main

warehouse to get a few parts. In these cases, sales associates agree to meet and move parts from

one sales van warehouse to another.

Warehouse Parts Inventory Update

The warehouse parts inventory update shall be done by processing an inventory delivery file just

like Project 1.

Sales Van Parts Inventory Update from Main Warehouse

When a sales associate visits the warehouse to load their van with parts, the sales associate

arrives with a sales van delivery file that describes the bicycle parts that are to be moved from

the main warehouse onto their van. The file consists of a sequence of comma-separated

lines. The first line contains the name of the main warehouse followed by the name of a

destination van, where parts are moved from the main warehouse to the destination. Each of the

remaining lines contains the name of the bicycle part and the quantity that is to be moved from

the main warehouse into the sales van warehouse. The following is an example.

Sales Van Parts Inventory Update from a Sales Van

When sales associate A meets with a sales associate B to get parts, sales associate A arrives with

a sales van delivery file that describes the bicycle parts that are to be moved from sales associate

Bs van into sales associate As van. The file consists of a sequence of comma-separated

lines. The first line contains the name of the source van followed by the name of a destination

van, where parts are moved from the source to the destination. Each of the remaining lines

contains the name of the bicycle part and the quantity that is to be moved from the source van to

the destination van. The following is an example.

When a sales van delivery file is processed in this case, the inventory in both the salesperson As

delivery van warehouse and salesperson Bs delivery van warehouse are updated.

NOTE1: Read this specification carefully. You must implement the program as described.

NOTE2: The Bicycle Parts Distributorship project specifications use the term database as a

general description of the underlying data that must be persistent across executions of your

program. To satisfy the persistent requirement, your database will have to be a file (or files) that

your program reads/writes. You do not have to create an SQL or NOSQL database.

Program Functional Requirements( The first 9 requirements are done by the five classes that I provide below. Please do the code to satisfy the last three requirments. Thank you very much.)

Your program shall accomplish the following. NOTE: Requirements 1 through 9 are identical

from Project 1; however, some implementation details such as filenames have been removed.

1. Your program shall have a warehouse database. The first time your program runs the

warehouse database shall be empty or nonexistent.

2. Your program shall read the warehouse database upon starting. This shall establish the

initial inventory in your internal data structures.

3. Your program shall write the internal data structures to the warehouse database upon

exiting. The inventory in your internal data structures shall be saved such that upon

running your program again, it starts with the same data as it ended with.

4. Your program shall read inventory delivery files (e.g., inventory.txt) as input by the

user. Reading inventory delivery files updates the data in your internal data structures as

follows.

a) If the bicycle part is not a member of your internal data structure, the bicycle part

is added.

b) If the bicycle part is is in your internal data structure, the list price is updated, the

sales price is updated, the on sale indicator is updated, and the quantity is added to

the current quantity on hand.

5. Your program shall show the bicycle part information by name.

6. Your program shall sell a bicycle part by part number from a warehouse. The sell shall

allow the user to specify the warehouse. When a bicycle part is sold, you shall do the

following for the specified warehouse.

a) Display the part name, the part cost, which will be either the list price of sale

price.

b) Display the time the part was sold.

c) Decrement the quantity.

7. Your program shall allow a new part to be entered interactively.

8. Your program shall display all parts in alphabetical order. This display shall show all

inventory attributes (name, number, list price, sale price, on-sale indicator, quantity). The

display alphabetical order shall allow specifying a particular warehouse as follows.

a) The total collection of warehouses

b) The main warehouse

c) Each individual sales van warehouse

9. Your program shall display all parts in part number order. This display shall show all

inventory attributes (name, number, list price, sale price, on-sale indicator, quantity). The

display part number order shall allow specifying a particular warehouse as follows.

a) The total collection of warehouses

b) The main warehouse

c) Each individual sales van warehouse

10. Your program shall allow the user to add a sales van to the fleet.

11. Your program shall allow a sales associate to move inventory from the main warehouse

into the sales van warehouse.

12. Your program shall allow a sales associate to move inventory from another sales van

warehouse into its sales van warehouse.

Object-oriented Requirements

1. Your program shall define and use a Java Interface as part of its solution.

2. Your program shall define and use inheritance as part of its solution.

User Interface Requirements

1. Your program shall have a JavaFX Graphical User Interface. The layout of the GUI

panels is your design, but I recommend you create a simple interface.
