Objective:

Work with multiple objects and

review reading data files.

Description

:

A wholesale distributor has six warehouses (Atlanta,

Baltimore, Chicago, Denver, Ely and Fargo) and sells five different items

(identified by

part number: 102, 215, 410, 525 and 711). Each warehouse

may stock any or all of the five items. The company buys and sells these items constantly. Company

transaction records contain a transaction code (P for a purchase or S for a sale) followed by an

item number

and the quantity (bought or sold).

The

transaction records are contained

in a transaction data file named Transactions.txt.

Sample transaction records:

Transactions.txt

P 410 1000

S 215 120

S 711 300

|

A separate data file contains the

initial status of the six warehouses at the beginning of the day (i.e., the ending

status from the night before). This data file has only six records (lines). Each record (line) contains five

numbers that show the quantity on hand for the five items in tha

t warehouse. This file is named

Inventory.txt

.

Sample status data file:

Inventory.txt

500 120 60 0 350

100 230 0 50 0

0 75 0 0 220

600 50 120 300 40

210 160 30 80 50

90 50 90 200 70

|

The status data file is updated by processing the transaction record

s in the transaction data file according to

these rules:

1

For a sale (S)

subtract the quantity sold from the warehouse that

has the largest supply of that item on hand.

2

For a purchase (P)

add the quantity purchased to the warehouse

that has the lowest supply of that item on hand.

Instructions:

Write an

object

-

oriented

Java program to do the above inventory warehouse processing. Each of the six

warehouses should be treated as an individual object. For example, Atlanta would be an o

bject with each of

the five part numbers as instance fields. Each of the other warehouses should also be objects with the five part

numbers as instance fields. Of course, there would be one class which would be the main

(driver)

class from

which these 6 ob

jects would be created.

In the beginning of the program, the status data file (

Inventory.txt

) should be read and an object for each

warehouse created. The

Inventory.txt

data file is in the following order: the first line is the Atlanta warehouse,

the sec

ond line is the Baltimore warehouse, third Chicago, then Denver, Ely and Fargo. After the objects are

created, the transactions data file (

Transactions.txt

) are read and processed.

The objects should be updated as the transaction records are read and

proce

ssed.

Create class Inventory and Driver Warehouses.

The program should

:

1

Display the initial (beginning

-

of

-

day) status for all warehouses.

2

Process each transaction from the transaction data file and show which

warehouses inventory was updated to reflect that transaction.

3

Dis

play the final (end

-

of

-

day) status for all warehouses.

Requirements:

The class must be named

Inventory

.

The main program (driver) must be named

Warehouses

.

A driver (main class) as well as a programmer

-

defined class must be used.

Submit program through t

he assignment tool in

Canvas

.

Include

a

comment

stating your name.

Each student must create his/her own independent program.
