🏦 Bank Management System (Java Swing)

Project Overview

The Bank Management System is a desktop-based Java application built using Java Swing to simulate fundamental banking operations. The project demonstrates object-oriented programming, GUI-based interaction, and file-based persistence without relying on external databases.

It is intended primarily for academic learning, focusing on how real-world banking workflows can be modeled using core Java concepts.

Objectives

• Practice Java Swing GUI development
• Apply OOP principles
• Implement event-driven programming
• Persist data using file handling
• Understand basic banking workflows in software form

---

Key Features

• Create new bank accounts
• Manage account details through a GUI
• Perform basic banking operations (deposit, withdrawal, transfers)
• Maintain persistent account records using text files
• Simple and intuitive graphical interface
• Background image integration for improved UI aesthetics

---

Technologies Used

• Language: Java
• GUI Framework: Java Swing
• Core Concepts:
  • Object-Oriented Programming
  • Event Handling
  • File I/O
• IDE: IntelliJ IDEA, NetBeans (IDE-specific files excluded via .gitignore)

Folder Explanation

• src/ – Core Java source files
• img/ – UI assets such as background and logo images
• data/ – Stores persistent application data such as account records and logs

---

How to Run the Project

1. Ensure Java JDK (8 or later) is installed

2. Open the project in IntelliJ IDEA

3. Verify that image files are present inside the img/ folder

4. Run the application from:

   src/Main.java
   

5. Use the GUI menu/buttons to perform banking operations

---

Data Storage

• All account information is stored in data/Accounts.txt
• Additional runtime data is maintained in data/filename.txt
• The file is automatically created and updated at runtime
• Data remains available across multiple executions

---

Known Limitations

• No database integration (text-file based storage only)
• No authentication or role-based access
• Limited input validation
• Not designed for production or real banking use

---

Possible Future Enhancements

• Integrate MySQL / SQLite database
• Improve exception handling and validations
• Refactor variable names for better readability
• Add user authentication (Admin / Customer roles)
• Improve GUI using layout managers (GridBagLayout, JavaFX)
• Add transaction history per account
• Encrypt stored data for security
