Preze Cinemas Desktop - Phase 4 Source Code

This repository phase contains the full implementation of the Preze Cinemas Desktop system.
Phase 4 focuses on transforming previous analysis and design phases into a working desktop application.

The system is implemented using:

• Java Swing for the desktop graphical interface
• JDBC for database connectivity
• MySQL databases for cinema and banking operations

1. Phase 4 Objective

The goal of this phase is to implement all previously modeled use cases as executable components of the system.

Each major use case is translated into a Java Swing Frame, enabling user interaction and system operations through graphical windows.

---

2. Implementation Overview

2.1 User Interface

The application uses Java Swing to build a desktop interface where:

• Each operation is represented as a separate window
• Navigation occurs between frames
• User inputs trigger database operations

Each use case corresponds to a dedicated class, such as:

• CheckAvailabilityFrame.java
• ChooseMovieFrame.java
• ChooseTicketsFrame.java
• ChooseTimeViewFrame.java
• PayFrame.java
• DownloadTicketsFrame.java

Example: CheckAvailabilityFrame.java checks ticket availability and determines whether the user can proceed to payment.

---

3. Database Connectivity (JDBC)

The system connects to MySQL databases through JDBC drivers.

Two databases are used:

3.1 Cinema Database

Stores:

• Movies
• Screenings
• Available seats
• Reservations
• Customer information

3.2 Bank Database

Simulates payment processing by storing:

• Customer banking information
• Account balances
• Transaction updates

---

4. Banking System Module

A separate module simulates an external bank system.

The BankSystem class performs:

• Transaction validation
• Account balance checks
• Payment execution
• Account amount updates

This module allows the cinema system to verify payments before completing reservations.

---

5. Core Functional Flow

1. User logs in or registers
2. User selects movie and screening
3. User selects tickets
4. System checks availability
5. Payment is validated via bank system
6. Reservation is completed
7. Receipt is generated

Each step corresponds to a frame interaction and database transaction.

cinemaapplication/banksystem/	Banking system simulation module
Frame.java files	UI windows implementing each use case

---

7. Phase 4 Outcome

At the end of this phase:

• All system use cases are implemented
• GUI interaction is functional
• Database communication is operational
• Payment simulation is integrated
• Reservation workflow is executable

This phase results in a fully functional desktop cinema reservation prototype.

---

8. Conclusion

Phase 4 completes the transition from system design to implementation, delivering a working application capable of managing cinema reservations, availability checks, and payment validation through an integrated desktop system.
