JavaFX Travel Expenses

Create a GUI application that calculates and displays the total travel expenses of a business- person on a trip. Here is the information that the user must provide:

• Number of days on the trip
• Amount of airfare, if any
• Amount of car rental fees, if any
• Number of miles driven, if a private vehicle was used
• Amount of parking fees, if any
• Amount of taxi charges, if any
• Conference or seminar registration fees, if any
• Lodging charges, per night

The company reimburses travel expenses according to the following policy:

• $38.00 per day for meals
• Parking fees up to $25.00 per day
• Taxi charges up to $49.00 per day
• Lodging charges up to $215.00 per day
• If a private vehicle is used, $0.49 per mile driven

The application should calculate and display the following:

• Total expenses incurred by the businessperson
• The total allowable expenses for the trip
• The excess that must be paid by the businessperson, if any
• The amount saved by the businessperson if the expenses were under the total allowed

Sample Output: see image.

Some notes:

For this you should either initialize each TextField to 0, or you must fill in each TextField before hitting the button.

The three formulas needed are:

double totalSpent = (days * nightlyLodging) + air + car +
(miles * PER_MILE) + parking + taxi +
(days * MAX_MEALS_PER_DAY) + reg;

double totalAllowable = (days * MAX_LODGING_PER_DAY) + air + car +
(miles * PER_MILE) + (days * MAX_PARKING_PER_DAY) +
(days * MAX_TAXI_PER_DAY) + (days * MAX_MEALS_PER_DAY) +
reg;

double excess = totalSpent - totalAllowable;

You should be able to line up these variables with the GUI TextFields.
