Bank Account OOP Application

The Bank Account OOP Application is a Java project that combines Class hierarchy and Polymorphism, built with Java 17+. The project follows a clean, modular architecture where input handling, business logic, and presentation stay separated, making it easy to test, extend, and present. It showcases practical Java techniques while producing a working, demo-ready application.

Manual and paper based methods for this task are slow, error-prone, and hard to manage. Without a Java application built on Polymorphism and Java 17+, users cannot process, store, and manage data efficiently, and there is no reliable, reusable way to run the workflow.

This project applies Java techniques through Class hierarchy, orchestrated with Java 17+ and Polymorphism. The application is designed for correctness and usability, with clean data flow, validation, and error handling. It produces consistent, reusable results and can be adapted to related tasks with minimal changes.

Modular Java application around Class hierarchy and Polymorphism Configurable settings and validation rules Clear logging, error handling, and reporting Clean interface for user interaction Reusable components for related features Unit testing and maintainable code

The project is layered: the input layer handles user interaction through Class hierarchy; the logic layer implements business rules with Java 17+ and Polymorphism; and the output layer presents results via Data models. Shared validation, storage, and logging modules support all layers, keeping the application robust and easy to extend.

Set up the Java project, dependencies, and environment. Build the input and model layer with Class hierarchy. Implement the core business logic using Java 17+ and Polymorphism. Add the output and presentation layer via Data models. Wire up end-to-end flows with validation and error handling. Write tests, run the application, and refine features. Package the project, document it, and prepare the demo and viva report.

The Bank Account OOP Application delivers a complete Java workflow — from input handling and business logic to output and presentation. It is practical, modern, and easy to explain, making it an excellent final year project that demonstrates in-demand Java skills.
