Your program development must include the following steps:

$1.$ Create a main GUI containing the following components:

a$.$ An area that allows the user to input data into the application along with the descriptive

text that describes each input area.

b$.$ An area that shows the current contents of the shopping cart.

c$.$ A total of six buttons as shown below with functionality as described below. The

various input fields and buttons on the interface are only accessible at certain points

during a user$$s interaction with the e$-$store.

$2.$ An input file named $$inventory$.$csv$.$ 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 five entries: an item id $($a string$),$ a quoted string containing the description of the

item, an in stock status $($a string$),$ the quantity on hand $($an integer$),$ 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 for testing purposes or augment the provided input file.

$3.$ An output file $($append only$)$ named $$transactions$.$csv$$ must be created that uniquely

identifies and 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$)$
