🏦 Smart Banking Management System

Hey there! 👋
This is a Smart Banking Management System that I built individually using Java and core Object-Oriented Programming (OOP) principles.

As a student, I noticed that most banking simulations are either too basic or purely text-based. I wanted to challenge myself by building something that feels more modern, gives users the freedom to choose their account type, and handles real banking logic in a structured way.

🌟 Why I Built This Project

I built this project to push myself beyond simple console programs and explore how real-world systems are designed.

My main goals were:

• Bridging the Gap: Designing a system that supports fully digital account creation
• Learning OOP: Applying inheritance and polymorphism to manage different card tiers
• Visual Learning: Creating a GUI-based application instead of a plain terminal program

This project helped me understand how backend logic and user interfaces work together.

🏗️ Class Architecture

BankSystem

Acts as the main controller that manages all user accounts and transactions.

Account (Abstract Class)

Contains common account logic shared by all account types.

StudentAccount / SilverAccount / GoldAccount / PremiumAccount

Subclasses that define specific withdrawal limits and behaviors.

Transaction

Records deposits, withdrawals, and transfers for transaction history.

👨‍💻 How to Run the Project

1. Clone the repository:

   git clone [your-repo-link]

2. Compile the main file: javac SmartBankSystem.java

3. Run the application: java SmartBankSystem

📚 Learning Outcome

This project strengthened my understanding of Java, OOP design, and GUI-based application development. It also helped me think more logically about how real banking systems manage users, security, and transactions.
