Build a Bank Management System in Java | OOP Concepts Explained | Dev Portal
Welcome back to Dev Portal!
In today's video, we’re taking a deep dive into a practical Java project — building a Bank Management System using Object-Oriented Programming (OOP) concepts. This tutorial will give you hands-on experience with classes, inheritance, polymorphism, and more to simulate a basic banking system with real-world features.
What you'll learn:
How to create an Account class as a base for multiple account types.
How to implement Savings Account and Current Account subclasses with unique features.
How to apply method overriding and use inheritance to customize behavior for different account types.
How to manage multiple accounts using a Bank class, and handle operations like deposit, withdrawal, and fund transfer.
Key OOP Concepts Covered:
1. Encapsulation: Securely store account details with private and protected fields.
2. Inheritance: Create specialized account types like Savings Account and Current Account.
3. Polymorphism: Override methods to customize functionality in subclasses.
Project Overview:
Entities: Account, Savings Account, Current Account
Operations: Create account, deposit, withdraw, check balance, transfer funds
Key Concepts: OOP fundamentals — encapsulation, inheritance, method overriding
Code Breakdown:
1. Step-by-step creation of base and subclass account types
2. Explanation of the Bank class to manage multiple accounts
3. Simulation of banking operations with real-world functionality
Extend the Project: Explore adding features like user authentication, account history, and more!
