Hi, previously I requested assistance with Java programming question. I now need to further modify the below code to add additional functionality. The requirements for specific functionality is below.
The customer is pleased with the first set of functionality and features added to the business application in Week 2. This week the customer wants you to add functionality and features to the application you created last week.
Modify the deliverable from Week 2 to:
- Include a combo box for the locations with five cities of your choice.
- Modify the food field to make it automatically place a value in that field based on the location selected.
- The values for the food field will be 70 when the first location is selected, 80 when the second location is selected.
- The food values will then increase by 5 for the remaining locations when selected.
- Add to the car field to allow for three rental car companies to select from using a radio button.
- The value for the cost of the rental car will remain as a text field.
This is the existing code requiring modification.
