UML Diagram
Class:
- LocalTour
Fields:
- numberOfTourist : int
- destination : String[]
- destinationCode : int
Methods:
- Tour()
- getInformation(Scanner scan) : void
- retrieveDestination() : String
- totalPrice() : double
- finalPrice() : double
- display() : String
The UML class diagram is based on LocalTour class.
A multi-location Tour company conducts sightseeing one day trips for groups from its home base.
For booking, their application accepts tour data, that includes:
- a numeric code that represents the destination
- The number of travelers taking the tour.
As data is entered for each tour, verify that destination code is valid. Continue to prompt the user until valid code is entered. Below are the valid code and an associated destination:
| Code | Destination |
| 1 | Chicago |
| 2 | Miami |
| 3 | Hawaii |
Ask for number of travelers after valid code is entered. Your program must be able to retrieve destination name using code. The company also offers discount on total price based on how many travelers are in a group. Discounts are calculated as:
| Number of Tourists | Discount per group |
| 1-2 | 0 |
| 3-6 | 100 |
| 7-12 | 200 |
| 13-20 | 400 |
| 21-50 | 500 |
Once processed, print destination code, destination name, number of travelers, gross total price for the tour and final price for the tour after discount.
Below are two sample output screen shots:
a) This one is for no discounts
Enter the numeric code for the destination: 5
Enter the numeric code for the destination: -1
Enter the numeric code for the destination: 2
Enter the number of travelers: 2
Destination name: Miami
Destination code: 2
Number of Travelers: 2
Gross total price for the tour: $1000.00
Final price for the tour after discount: $1000.00
b) This one is with discount
Enter the numeric code for the destination: 1
Enter the number of travelers: 10
Destination name: Chicago
Destination code: 1
Number of Travelers: 10
Gross total price for the tour: $5000.00
Final price for the tour after discount: $4800.00
