Java Backend Learning Journey 🚀

This repository is dedicated to my journey of learning Java programming fundamentals, Object-Oriented Programming (OOP), and Spring Boot for building robust backend applications.

📌 Goals & Roadmap

1. ✅ Java Fundamentals

   • Variables, Data Types, Control Flow
   • Functions, Arrays, Collections
   • Exception Handling

2. ✅ Object-Oriented Programming (OOP)

   • Classes & Objects
   • Inheritance, Polymorphism
   • Abstraction, Encapsulation

3. 🔜 Spring Boot

   • Setting up REST APIs
   • Project Architecture (Controller, Service, Repository layers)

4. 🔜 Database Integration

   • PostgreSQL (Hosted on Neon)
   • Database schema and migrations using Flyway or Liquibase

5. 🔜 CRUD Operations

   • Building API endpoints
   • Performing Create, Read, Update, Delete operations

6. 🔜 API Testing

   • Using Postman or cURL for endpoint testing

7. 🔜 Advanced Features

   • Pagination & Filtering
   • Authentication (Optional)
   • Clean Code & Best Practices
