✨ Highlights

• 🧭 Domain to IP resolver using InetAddress
• 🪑 Seat selection buttons with confirmation prompts
• 🖥️ Simple Swing UI (no external dependencies)
• 🧩 Single-file app (easy to read and extend)

✅ Prerequisites

• ☕ Java 8+ (JDK installed)
• 🧰 Command-line tools (javac, java) in your PATH

Check your Java version:

java -version

🚀 Run the App

From the project root:

javac src/FlightBookingDemo.java
java -cp src FlightBookingDemo

🧪 Optional: Build with Ant

If you prefer Ant and have it installed, you can use the provided build.xml:

ant

This will compile the project and generate build outputs per the Ant configuration.

🧑‍💻 How to Use

1. Enter an airline domain (e.g., flyair.co.za).
2. Click Resolve IP to see resolved addresses.
3. Choose a seat (1A, 1B, or 1C) and confirm your selection.

⚙️ Configuration Tips

• Domain input: Any valid domain works; try example.com if you want a quick test.
• Seat behavior: Once a seat is confirmed, the button is disabled for that session.
• Networking: Resolution requires internet access or a resolvable local DNS entry.

🧩 Main Entry Point

• src/FlightBookingDemo.java contains the Swing UI, event handlers, and main method.

🛠️ Troubleshooting

• “Could not resolve” error: Make sure the domain is valid and you have network access.
• Compilation errors: Confirm you’re using Java 8+ and compiling from the repository root.
• App doesn’t open a window: Ensure you’re running on a machine with a GUI environment.

📌 Notes

• This app is a demo and stores no data.
• Seat selection disables the chosen seat for the current session.
• The UI is intentionally minimal for learning and extension.

Enjoy flying! ✈️
