Program Description
You will be writing a small inventory manager program. The informa-
tion about what stock you have on hand is stored in a le. Your program will read the
items you have in stock from a le. Each line read from the le will be an Item object.
There will be 10 in total. The Item objects created MUST be stored in an Array of
Item objects. The array size will be 10. Once your inventory is loaded your program
will do the four following operations:
1 Print Inventory
2 Check for low Inventory
3 Print Current Value of Inventory
4 Exit Program.
Assignment Steps:
1 Setting up Project:
1.1 Create a Project named InventoryManager
1.2 Add a file named Item to your project.
1.3 Download the items le from ilearn under the assignment PDF.
Paper 10 5.99
ColoredPaper 10 6.99
PaperClips 55 0.99
Staples 1000 0.10
Chairs 3 49.99
Pens 500 0.75
Pencils 500 .10
Highlighters 100 1.00
Toner 2 69.99
Post-its 100 1.99
1.4 Copy/Move the le to the project folder named InventoryManager. This
should be inside your NetBeans Project Folder.
2 Implement Item.java Class:
2.1 Create three data elds : name , quantity, and price per unit. Make
sure all data elds are private and have the appropriate type.
2.2 Create a no-arg constructor that initializes NO data elds and a constructor
that initializes ALL data elds.
2.3 Create all getters and setters for each data eld.
2.4 Implement a toString method that builds a nicely formatted string represent-
ing an Item object. REMEMBER YOU ARE NOT ALLOWED to print from
this method. IT MUST return a String.
3 Implement InventoryManager.java Class, do the following:
{ Write a class method called printInventory which takes an Array of Items as
its parameter. This method will print the entire inventory to the console. It
should print in the following way:
Name Quantity Price Per Unit
Paper 5000 .10
{ Write a class method called checkLowInventory which takes an Array of Items
as its parameter. This method checks for items that have fewer quantity than
5, and prints them in the same format as printInventory does. If there is no
such item then print an appropriate message.
{ Write a class method called totalInventoryValue which takes an Array of
Items as its parameter. This method computes the total value of the current
inventory using the quantity and price per unit information, and prints that
total value to the console.
In the main method:
3.1 Use File class and Scanner class to read the items and related information
from the le provided with this assignment. It is available on ilearn.
3.2 For every item in this le create a new object of the Item class with appro-
priate values.
3.3 Let all the objects be a part of an array. There are 10 items in the le.
3.4 Then print the following menu to the console :
PrintInventory (p)
Check Low inventory (c)
Print Total Value of inventory (v)
Exit (e)
3.5 Prompt the user to enter an option. Read this option in as a char. You can
assume they will enter a lower case character and that the input will be valid.
3.6 Depending on the option entered you will do the following:
If the user enters p, call printInventory method
If the user enters c, call checkLowInventory method
If the user enters v, call totalInventoryValue method
If the user enters e, Program Exits
3.7 Loop steps 3.4 to 3.6 until the user enters e as an option.
