Need help!!!!! is java code plz!!

Inheritance and

Interfaces

Overview

In this homework, you will implement a system that

A????1 reads in an inventory file,

A????1 prints the inventory to the console, and

A????1 ships items.

It requires you to use Java classes and interfaces rather than static functions as we did in previous homework.

Basic Application

In this homework, you will create the basic application that reads input from a datafile and writes the results to the console. In the next homework, you will enhance the application by adding database functionality.

Program Flow

The following pseudocode shows the required flow of the program.

Begin

for each   line   in   inventory   file   do

determine   inventory   type

based   on   type,   create   object   to   hold   data   (FoodItem   or   Household   Item)

populate   item   with   appropriate   data   (weight,   etc)

store   in   inventory   list

end

for each   item   in   inventory   list   do

print   item   

end

for each   household   item   in   inventory   do

determine   shipping   cost print   shipping   cost

End

end

^{Program Output}

For the supplied input file, the output should be as shown below (dates will be different!)

Item banana

-- Shelf Life: 5

-- Remove from Shelf: Thu Mar 12 22:07:56 CDT 2015

-- Calories: 200.00

Item bread

-- Shelf Life: 10

-- Remove from Shelf: Tue Mar 17 22:07:56 CDT 2015

-- Calories: 120.00

Item toaster

-- Weight: 5

Item washer

-- Weight: 200

Item toaster shipped. Shipping cost is $100.00

Item washer shipped. Shipping cost is $4,000.00

Business Rules

There are two types of items tracked in the system: food items and household (durable) items.

A????1 Food Items

Food items are edible (we hope!) and perishable. An edible item has calories, while a perishable item has a limited shelf life. The item must be removed from the shelf when it expires. The expi- ration date is simply

expiration date = date placed in inventory + shelf life in days

A????1 Household Items

Household items have unlimited shelf life, so they do not have an expiration date. They do have (sometimes substantial) weight. Their weight is taken into account when determining the ship- ping cost. The shipping cost is also higher when the item is shipped on the weekend.

UML Diagram

The classes and interfaces required for the application have been defined for you, and are shown in the diagram below. Dotted lines indicate interfaces while solid lines indicate inheritance. Your application must implement all classes and interfaces as shown.

 

Javadoc

The Javadoc for the application has been generated for you and is available in Blackboard as a zip file. Unzip the file into a directory and then open the file index.html to view the documentation.
