project will be to implement a shopping cart class with user interface (UI) that contains main() in Net Beans. The UI class will be used to perform user input/output and to invoke the appropriate methods of shopping cart class. When your program starts, it will automatically open the shopping cart window by asking username and password of sale personal. After the login page successfully entered; next, the following shopping cart must be displayed:

1) List of items available in the store: Used the button (in Net Beans) to set the name of the items and set the price of the items. (Example: Polo shirt = RM120.50, Jeans = RM150.00)

2) The cart will click on the items button displayed and the total price will be displayed at the bottom of the page.

3)The sale personal will key in the amount of money received by customer.

4) The cart will show the balance return to customer.

5) Once the process done, the page should go back to list of items page to accept new sale. Sample UI Note: The list of items must be more than 5 and less then 10 items.
