Develop a Java application that simulates a flight ticket booking system with a graphical user interface (GUI) using Swing components. The application should enable passengers to select their preferred class (First, Business, Economy), specify the number of seats, and choose between a one-way or two-way trip. Based on these inputs, the program will calculate and display the total price, considering predefined costs for each class and trip type.

The program must demonstrate key Object-Oriented Programming (OOP) principles including inheritance, polymorphism, abstract classes, and interfaces. It should utilize Swing controls such as JComboBox for class selection, JRadioButton and ButtonGroup for trip options, JTextFields for input and output display, JPanels for organizing components, and JButtons for user interactions. Additionally, include at least two Swing topics such as Icons, Scrollbars, Fonts, Colors, or Listeners, along with one new control with an associated event not covered in the course.

The application's core logic involves creating a Passenger object, passing user-selected attributes like name, class, number of seats, and trip type through an appropriate constructor. This object performs the price calculations based on class, seat count, and trip type, ensuring input validation by handling exceptions for empty fields, negative or zero values. The GUI should display the calculated total, accommodating multiple passengers if necessary.

Include comprehensive program listing, sample output demonstrating various scenarios (valid input, empty fields, invalid values), and relevant references to Java programming resources. Follow the provided guidelines for project documentation, including cover page, table of contents, introduction, resource specifications, program code, outputs, and references. The project aims to reflect well-designed, user-friendly, and creative use of Java Swing and OOP concepts in application development.

Paper For Above instruction

The development of a flight ticket booking system using Java Swing exemplifies the application of object-oriented programming (OOP) principles, along with GUI design to create an interactive and user-friendly interface. This project integrates inheritance, polymorphism, abstract classes, and interfaces to manage the different components of the system, providing a robust framework for handling passenger data and fare calculations.

At the core, the application models passengers and reservations through classes and interfaces. An abstract class 'Reserv' defines the common attributes such as number of seats, trip type, and price, while the interface 'Classes' provides constants for different flight classes and methods for retrieving class information. The 'Passenger' class extends 'Reserv', adding passenger-specific attributes such as name and implementing the method to calculate fare based on class, seats, and trip type. This hierarchy encapsulates data and behaviors, facilitating code reuse and scalability.

The GUI employs Swing components to facilitate user input and output. A JComboBox displays the available flight classes: "First Class," "Business Class," and "Economy Class," each mapped to their respective fare constants. JRadioButtons grouped within a ButtonGroup allow selection of trip type: one-way or two-way. JTextFields serve for entering passenger names, number of seats, and showing the calculated total fare. JPanels organize these components, while JButtons enable users to trigger calculations or reset inputs. Additionally, the interface includes controls such as icons or custom scrollbars to enhance visual appeal, and event listeners to handle user actions efficiently.

The application workflow involves capturing user selections and inputs, instantiating a 'Passenger' object with these parameters, and invoking methods to compute total fares considering class rates, number of seats, and trip type. Input validation is critical; the program checks for empty inputs, non-positive seat counts, and invalid data, providing appropriate error messages or exception handling to guide users toward correct data entry. When calculations are successful, the GUI displays the total cost, formatted neatly for clarity.

Sample outputs illustrate various scenarios: a passenger selecting economy class with three seats and a one-way trip might pay a specific amount, while leaving fields empty or entering negative numbers prompts error messages. This demonstrates the application's robustness and user-centric design, ensuring smooth operation under diverse input conditions.

Extending the project further, developers can incorporate features like saving reservations to files, integrating with databases, or adding advanced GUI controls such as color selectors or font pickers, which utilize Swing's extended capabilities. The final product exemplifies how Java's OOP features and Swing GUI components coalesce to produce an intuitive flight reservation system.
