Question
Implement the Swing application using the GUI you designed in the Phase 1 Discussion Board. The user will have to enter the following data items:
Sales representative ID
Sales representative First Name
Sales representative Last Name
Total sold for each of three categories: office supplies, books, and paper
Sales district (North, South, East, West).
Preferred means of contact with potential buyers (phone, e-mail, visit)
Include a QUIT button to exit the application and an ENTER button that causes the sales representative’s data to be retrieved from the GUI components and submitted to the application. The sales representative’s data will echo to the jTextArea each time the ENTER button is pressed.
Your application should be thoroughly commented.
