Part 1: Wk 2 Assignment: GUI and Input, Output, and Variable
Assignment Content: Create Java™ travel authorization request graphical user interface (GUI) application via NetBeans to calculate the cost of a business trip.
- Include the following functionality:
- Traveler name (text field)
- Airfare cost (text field)
- Food cost (text field)
- Hotel cost (text field)
- Car cost (text field)

- Button
The user will enter the name of the traveler and the cost of each item for a trip request. When the user clicks the calculate button, 10% of the total amount will be added to the trip total and be displayed in the Summary field. The use of variables are required to store the costs of the individual items. Submit your assignment as follows the Netbeans cut/paste the source to a MS Word document and a screen shoot of the output.
Part 2: Wk 3 Assignment: GUI and Input, Output, and Variable
Assignment Content:
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 and 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.
Week 3 Assignment Output is only required. With Screen shot of Output

In this project, a JFrame was used for the GUI. Here, the inputs and outputs will be displayed.
EventListeners and ActionListeners were also used for the functionality of the system.
