🏦 Bank Management System (Java)

📘 Project Overview

The Bank Management System is a simple console-based application developed in Java as part of the Object-Oriented Programming in Java (OOPJ) course at C.V. Raman Global University, Bhubaneswar.
It demonstrates how object-oriented concepts such as classes, inheritance, encapsulation, and polymorphism can be used to design and implement a real-world banking system.

This project provides a streamlined way for managing customer accounts, handling deposits, withdrawals, and checking account balances — simulating basic banking operations efficiently.

🧩 Features

• Account creation with admin authentication
• Deposit and withdrawal operations
• Balance inquiry and account details display
• PIN-based customer security
• Simple text-based user interface
• Real-time transaction tracking within the session

🚀 How to Run

1. Clone or download this repository.

2. Open the project in your preferred IDE.

3. Make sure JDK 8 or later is installed.

4. Compile and run the file:

   javac BankManagementSystem.java
   java BankManagementSystem
   
   

5. Follow the on-screen instructions to:

   • Create a bank account
   • Deposit or withdraw money
   • Check balance or account details

🔐 Default PINs

• Admin PIN: 1234
• Customer PIN: 123456

These can be modified within the source code for added customization.

📊 Workflow

1. Admin creates an account using admin PIN.
2. Customer logs in using their 6-digit PIN.
3. Customer performs transactions (Deposit / Withdraw / Check Balance).
4. System displays updated transaction details.

📈 Future Enhancements

• Integration with a database (MySQL / SQLite) for persistent storage
• GUI development using JavaFX or Swing
• Multi-customer support
• Transaction history logging
• Enhanced security and error handling

Would you like me to tailor the README for **GitHub formatting** (badges, visuals, table of contents, and screenshots placeholders)? It would make it look more polished for portfolio use.
