Retail Calculator

  A retailer would like a calculator to indicate
sale prices when he marks items down at various percentages.


  Design, implement, test, and debug a GUI
application that allows the retailer to enter the item’s name, the item’s
original price, and the percentage discounted.


  The application should include a Calculate
button that, when pressed, computes and displays the sale price in a label or
text field.


  The program should allow the retailer to enter
any number of items in this manner.

  Include an Exit button to end the execution of
the application.

  The program should allow the user to select a
department from a menu.

  You may create the menu as a true menu, a
JComboBox, or radio buttons.

  Create your own list to populate the menu: men’s
clothing, women’s clothing, house wares, and so forth.

  Include at least five departments.

  Create a JTextArea or a JTable to display each
of the following for each item entered.


  Item name


  Original price

  Sale price
