JAVA

Inheritance and Interfaces

Overview

In this homework, you will implement a system that reads in an inventory file, prints the

inventory to the console, and ships items.

Business Rules

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

Food Items: Food items are perishable, and a perishable item has a limited shelf life. The item must be removed from the shelf when it expires. The expiration date is simply

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

Household Items: Household items have unlimited shelf life, so they do not have an expiration date. They do have (sometimes substantial) weight. The shipping cost is

$10.00 / pound. If the item is shipped on a weekend day, the shipping cost should be increased by $20.00.

Example: a 20 pound item shipped on Saturday would have a shipping cost of

$220.00.

Program Design

Input

The program will take as input a file formatted as follows:

food,banana,5 food,bread,10 household,toaster,5 household,washer,200

The first element in a line is the type of item: food or household good. If the item is a food item, the second element is the name, the third is the shelf life in days. If the item is a household good, the second element is the name and the third is the shipping weight in pounds.

You will create an input file with the data above called "input.txt". When you load the file you should not use a full path.

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

request shipping date from user

for each household item in inventory do

determine shipping cost based on shipping date print shipping cost

end

End

Output

The output of the program for the input above would be

Item banana

-?-? Shelf Life: 5

-?-? Remove from Shelf: Fri Oct 10 19:37:29 CDT 2016 Item bread

-?-? Shelf Life: 10

-?-? Remove from Shelf: Wed Oct 15 19:37:29 CDT 2016 Item toaster

-?-? Weight: 5 Item washer

-?-? Weight: 200

Please enter a shipping date: March 16, 2016

Toaster will be shipped on March 16, 2016. Shipping cost is $70.00. Washer will be shipped on March 16, 2016. Shipping cost is $2020.00.

NOTE: The remove from shelf dates are based on the date the program is run. They will not be the same as those shown above.

UML and Javadoc

The classes and interfaces have been specified for you, and are documented in the UML diagram below and in Javadoc. The Javadoc for the project is available online

as a zipped directory and on the web at http://162.243.207.40/.(This is the website where the files can be found for this program)

Approach

Start by creating all the classes and interfaces and their methods and propertieswithout worrying about what the methods do. When you have this code compiling, go back and implement the methods. For each class and method, read the relavent portion of the Javadoc and look at where it fits in the overall flow of the program (see the pseudocode).

NOTE: I need help creating the JAVA CODE NOT THE PSEUDOCODE.... I would really appreacite it if someone can help me with this.

Thank you in advance
