1.Construct   an   interactive   Java   Graphical   User   Interface   (GUI)   Application.   This application should be based on the JFrame class and uses SWING GUI components.

 

The task is to develop a Java Application which will make it possible for users to make bookings for holidays, accommodation as well as flights and meals before travelling. This booking process will involve selecting options from three lists which are in drop-down format. Assume that flight, accommodation and meals are always selected by the users. The GUI for the application should be as shown below, with the components laid out in like manner (i.e. in the same order).

 

The booking should be stored in a text file. The program should show the bookings made from the text file.

Description of the 3 functions:

 

Function 1: Process Booking:                                                                                [4 marks]

The  “Process  Booking”  button  calculates  and  sums  up  the  cost  of  selected  flights, accommodation as well as meals. A dialog box should pop out after calculations are done,

 

 

Table a. Accommodation

 

 

 

Accommodation	Cost (P)
Motel	150
2 Star Hotel	250
3 Star Hotel	550

 

 

Table b. Flights

 

 

 

Flights	Cost (P)
London	1400
Dubai	400
India	1800

 

 

Table c. Meals

 

 

 

Meals	Cost (P)
All meals	100
Breakfast	20
Lunch	35
Dinner	45

 

 

 

 

 

Function 2: Show Booking Cost                                                                                [4 marks]

 

Upon pressing the ‘Show Booking Cost’ button the total booking cost for the overseas holidays should be displayed, i.e. the cost of flights plus accommodation costs plus cost of meals as shown below:

 

 

 

 

Function 3: Exit                                                                                                  [4 marks]

 

The “Exit” button should allow the user to exit from the application.

 

 

 

 

Hint: Your application MUST have at least  two Classes (Booking and Booking

Application)

 

The class Booking should have the following:

The  class  booking  should  have  variable  and  constant  declaration,  a  constructor  to initialize variables and three (3) methods,

 

1. To accept index from flight array and return flight cost

 

2. To accept index from accommodation array and return accommodation cost

 

3. To accept index from meal array and returns meal cost

 

 

 

 

The class Booking Application should have the following:

Declaration

Declare variables and constants

 

Declare three arrays of type string to store flights, accommodation and meals

 

Declare window width and height

 

Constructor

 

Use JFrame super class to set the window title

 

Create an instance of booking object

 

Call method to create 1 level, 3 combo boxes and 3 buttons

 

Call method to create panels and add label, combo boxes and buttons to panel

 

Add a panel to frame and make it visible

 

Method1

 

Create greeting label, 3 combo boxes (1 for flights, 1 for accommodation and 1 for meals)

and 3 buttons. Register the action listeners

 

Method2

 

Create panel and add components (1 level, 3 combo boxes, 3 buttons) Other

Inner listener class for flight combo box

 

Inner listener class for accommodation combo box

 

Inner listener class for meal combo box

 

Inner listener class for Process Booking Button Inner listener class for Show Booking Cost Button Inner listener class for Exit Button
