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!
