I have a project to work on during class time. You will present your application to the class next week. There is a drop box for you to upload your completed assignment document. Each team member will upload a document with screen shots of code and some sample runs. Each team member will contribute with ideas, syntax, energy, and perhaps a share of the typing. Good time management is essential as time is limited.

As well as logical, you need to be creative in your software development. This week you will WOW! the class with an application of your own design, on the subject of Travel Guide or Trip Planning.

Searching online for the geographic information you need.

Your presentation should be fun and informative or perhaps useful.

Include the following: arrays and collection processing, input validation and exception handling, date processing and calculations, output formats, great user experience including some graphics and maybe animation, PLUS all the default requirements such as good GUI layout, tabbing, Enter and Esc keys, object/control naming, and documentation!

Solution

Travel Expenses for travel trip gui:

This a GUI application calculates and displays the total travel expenses of a business person on a travel trip. Here is the information that the user must provide:
• Number of days on the travel trip
• Amount of airfare for travel trip, if any
• Amount of car rental fees for traveling, if any
• Number of miles driven for travel, if a private vehicle was used
• Amount of parking fees travel , if any
• Amount of taxi charges travel , if any
• Conference or seminar registration fees for travel, if any
• Lodging charges, per night for travel

The company reimburses travel expenses according to the following policy:
• $37 per day for meal travel(this is given regardless of if used so no text field is needed for input)
• Parking fees for travel , up to $10.00 per day
• Taxi charges for travel up to $20.00 per day
• Lodging charges for travel up to $95.00 per day
• If a private vehicle for travel is used, $0.27 per mile driven

This application should calculate and display the following:
• Total expenses incurred by the businessperson for travel
• The total allowable expenses for the travel trip
• The excess that must be paid by the businessperson for travel trip, if any
• The amount saved by the businessperson for traveltrip if the expenses were under the total allowed
