Description
: Develop a Java program that creates a standalone GUI application that simulates an e-store (we’ll call our store Nile Dot Com… we’re not quite as big as Amazon.com!)[1] which allows the user to add in stock items to a shopping cart and once all items are included, total all costs (including tax), produces an invoice, and append a transaction log file.
Your program development must include the following steps:
- Create a main GUI containing the following components:
- An area that allows the user to input data into the application along with the descriptive text that describes each input area.
- A total of six buttons as shown below with functionality as described below.
- As illustrated below, the various buttons on the interface are only accessible at certain points during a user’s interaction with the e-store.
- An input file named “txt”. This is a comma separated file which contains the data that will be read by the application when the user makes a selection. Each line in this file contains three entries; an item id (a string), a quoted string containing the description of the item, and the unit price for one of the item (a double). A sample file is provided for you on WebCourses. Feel free to create your own input file.
- An output file (append only) named “txt” must be created that uniquely logs each user transaction with the e-store. The unique transaction id will be generated as a permutation of the date/time string when the transaction occurred (see below).
