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

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.

---

Implementation Overview

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.

---

Database Connectivity (JDBC)

The system connects to MySQL databases through JDBC drivers.

Two databases are used:

Cinema Database

Stores:

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

Bank Database

Simulates payment processing by storing:

• Customer banking information
• Account balances
• Transaction updates

---

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.

---

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/	Main application source code
cinemaapplication/banksystem/	Banking system simulation module
Frame.java files	UI windows implementing each use case
database/	SQL schema or setup scripts (if included)
README.md	Project documentation

---

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.

---

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.

Installation & Setup Guide – Preze Cinemas Desktop (Phase 4)

This guide will help you set up and run the Preze Cinemas Desktop application on your local machine.

---

Prerequisites

Software Requirements

• Java Development Kit (JDK 11 or later)
  • Download: https://www.oracle.com/java/technologies/javase-jdk11-downloads.html
• NetBeans IDE (or any Java IDE supporting Swing & JDBC)
  • Download: https://netbeans.apache.org/download/index.html
• MySQL Server (≥ 8.0 recommended)
  • Download: https://dev.mysql.com/downloads/mysql/
• MySQL Workbench (optional, for database inspection)
• Git (optional, for cloning the repository)

Optional Tools

• Command-line terminal
• Text editor for configuration file edits

---

2. Clone the Repository

git clone https://github.com/Preze-Cinemas-Desktop/Code.git
cd Code

The project folder structure:

assign/
CinemaApplication/
README.md

CinemaApplication/ contains:

• src/ → Java source files for GUI and business logic
• build/ → compiled .class files
• nbproject/ → NetBeans project files
• build.xml → build script
• manifest.mf → JAR packaging file

3. Set Up MySQL Databases

The application requires two databases: cinema and bank.

3.1 Create Databases

1. Log in to MySQL:

mysql -u root -p

2. Create databases:

CREATE DATABASE cinema;
CREATE DATABASE bank;

3.2 Import Schema and Sample Data

If .sql scripts are provided in the repository (e.g., CinemaApplication/database/), import them:

mysql -u root -p cinema < cinema_schema.sql
mysql -u root -p bank < bank_schema.sql

If no scripts are provided, manually create tables according to the project documentation:

• Cinema Database Tables: movies, screenings, seats, reservations, customers
• Bank Database Tables: accounts, transactions, balances

4. Configure Database Connection in Java

Open the main configuration file (or CinemaApplication.java/BankSystem.java) and check the JDBC connection strings:

String urlCinema = "jdbc:mysql://localhost:3306/cinema";
String urlBank = "jdbc:mysql://localhost:3306/bank";
String user = "root";
String password = "your_mysql_password";

Update the username and password to match your MySQL setup.

5. Open Project in NetBeans

1. Launch NetBeans IDE.
2. Click File → Open Project.
3. Navigate to CinemaApplication/ and select the folder.
4. NetBeans should detect the project as a Java application.
5. Wait until the IDE fully loads the project and resolves dependencies.

6. Build the Application

1. Right-click the project → Clean and Build.
2. Check for compilation errors in the Output window.
3. The executable .class files will be generated in build/.

7. Run the Application

Right-click the main class CinemaApplication.java → Run File.

Or run from command line:

cd CinemaApplication/build/classes
java cinemaapplication.CinemaApplication

8. Using the Application

1. Login or Register: Start by creating a new user or logging in.
2. Choose Movie: Select a movie and screening time.
3. Select Tickets: Pick the number and type of tickets.
4. Check Availability: Ensure tickets are available.
5. Payment: Simulated via BankSystem.
6. Download Receipts/Tickets: Save outputs as .txt.

9. Troubleshooting

• JDBC Driver Not Found: Ensure mysql-connector-java.jar is in the classpath.
• Database Connection Error: Verify credentials and MySQL service status.
• GUI Issues: Use NetBeans’ “Clean and Build” to resolve corrupted Swing layouts.
• Payment Validation Errors: Ensure bank database contains sufficient account balances.
