What You'll Build: The Bank Account Management System

A Fully Functional, Secure, and Scalable Application

This isn't just a simple "To-Do" app. You will architect and develop a robust banking application that handles core financial operations. This project serves as a powerful portfolio piece, demonstrating your ability to build complex, data-driven systems.

Throughout the course, you'll implement key functionalities that mirror real-world banking software, providing you with a tangible and impressive result to showcase to potential employers.

  • Customer Management: Onboard new customers and view their details.
  • Multi-Account System: Create and manage savings and checking accounts.
  • Core Transactions: Implement logic for deposits, withdrawals, and transfers.
  • Transaction History: Build an API to fetch and display a record of all transactions.
  • Secure Authentication: Implement a robust login system with encrypted passwords using Spring Security.
  • Role-Based Access Control: Differentiate between customer and admin roles for secure data access.
  • RESTful API Architecture: Design and build a clean, well-structured API for all banking operations.

Comprehensive Course Curriculum

A step-by-step journey from Java fundamentals to deploying a complete Spring Boot application.

Welcome to the world of enterprise software! In this foundational module, we answer the big questions: What is Java and why has it dominated the enterprise landscape for decades? We then introduce its modern accelerator, Spring Boot, and explain how it revolutionizes development speed and efficiency. You'll get a high-level overview of our capstone project—the Bank Account Management System—and, most importantly, we'll guide you through setting up your complete professional development environment, including the Java JDK, IDEs like IntelliJ or Eclipse, and build tools like Maven.

Every great structure needs a solid foundation. This module ensures you have a strong command of the core Java principles. We'll revisit variables, data types, and control structures (if/else, loops). We dive deep into the heart of Java—Object-Oriented Programming (OOP)—by mastering Classes, Objects, Methods, and Constructors. You'll learn about Encapsulation to protect your data, powerful Collections like Lists and Maps to manage it, and robust Exception Handling to build resilient code. We'll cap this module by building a simple console-based banking app to immediately apply these concepts.

Now, the magic begins! You'll create your very first Spring Boot project using the Spring Initializr and understand its clean, convention-over-configuration structure. We'll demystify the core architectural pattern: Controllers, Services, and Repositories. This is where you'll learn about REST APIs—the backbone of modern web services. By the end of this module, you'll have built your first "Hello World" REST endpoint and learned how to test it using Postman, an essential tool for any backend developer.

Applications are nothing without data. This module teaches you how to connect your Spring Boot application to a database. We'll cover the basics of relational databases like MySQL or H2. You'll learn about the powerful duo of JPA (Java Persistence API) and Hibernate, the industry-standard Object-Relational Mapping (ORM) tool that lets you interact with database tables as if they were simple Java objects. We'll define our `Account` and `Customer` entities and use the magic of Spring Data JPA to write full CRUD (Create, Read, Update, Delete) operations with minimal code.

With our foundation and database connection in place, it's time to build the core features of our banking application. We'll implement the business logic for Customer Management (adding new customers, viewing details), Account Management (opening new accounts), and essential Transactions (depositing, withdrawing, and transferring funds between accounts). We will also build a dedicated API endpoint to retrieve a complete history of transactions for any given account, reinforcing your API design skills.

Security is not an afterthought; it's a necessity. In this critical module, you'll be introduced to Spring Security, the ultimate framework for securing Spring applications. You will build a complete user authentication system from scratch, allowing users to log in. We'll go a step further by implementing role-based access control, ensuring that regular customers can only see their own data while an admin has broader permissions. You'll also learn the non-negotiable practice of password encryption using BCrypt to protect user credentials.
