Spring is the industry standard for Java backend.
GFG Learning Path: Start with the "Java Tutorial" section. Complete all "Easy" and "Medium" level problems under the "OOPS" and "Collections" tags.
To master backend, you must build. Here are 3 projects (increasing difficulty):
| Level | Project | Concepts Covered | |-------|---------|------------------| | Beginner | Todo App with User Auth | Spring Boot, JPA, Spring Security, JWT | | Intermediate | E-commerce Backend (Products, Cart, Orders) | REST, Pagination, Redis caching, Stripe/PayPal integration | | Advanced | Real-time Chat & Notification System | WebSockets, Kafka, MongoDB, OAuth2, Microservices |
Before touching backend frameworks, GFG ensures you master the language itself.
GFG recommends Maven for beginners due to structured XML and large community support.
A well-structured Java Backend Development track on GeeksForGeeks should combine solid core Java teaching, practical Spring Boot API development, database handling, testing, and real-world deployment practices—culminating in a capstone project that demonstrates end-to-end backend skills and readiness for entry-level backend roles.

It features a blend of live classes, AI-assisted coding, and capstone projects. 🛠️ Course Roadmap Spring is the industry standard for Java backend
The curriculum is structured to take learners from core fundamentals to complex microservices. Phase 1: Java Mastery (Weeks 1–3)
OOP Fundamentals: Classes, Inheritance, Singleton patterns, and Exception handling.
Modern Java: Functional interfaces, Lambda expressions, and Java 8 Streams.
Advanced Core: Multithreading, HashMaps, and Sequential vs. Parallel execution. Project Tools: Managing builds with Maven and Gradle. Phase 2: Frameworks & APIs (Weeks 3–6)
Spring Boot Basics: Server/Client models, Embedded servers (Tomcat/Jetty), and Spring Profiles.
RESTful Services: Handling HTTP requests, using Postman, and mastering Lombok.
Persistence: JDBC, Hibernate ORM, JPA, and writing custom JPQL queries. Quality Assurance: Unit testing using JUnit and Mockito. Phase 3: Scaling & Security (Weeks 7–12) Caching: Performance optimization with Redis. GFG Learning Path: Start with the "Java Tutorial" section
Security: Authentication, Authorization, and GitHub OAuth 2.0 integration.
Architecture: Monolithic vs. Microservices and Load Balancing algorithms. Messaging: Real-time data streaming with Apache Kafka. 🚀 Hands-on Projects You will build three portfolio-ready applications:
Digital Library (Minor): Focuses on data modeling, JPA relationships, and basic CRUD.
Movie Review/Ticket Booking (Minor): Implements REST APIs and user interactions.
E-Wallet App (Major): A Paytm-like app using Microservices architecture, focusing on scalability and secure transactions. ✨ Key Highlights
AI Integration: Learn to use AI tools like Cursor to generate boilerplate code and refactor logic.
Career Support: Access to a Private Job Portal and 1:1 doubt-solving sessions.
Certification: Industry-recognized certificate upon completion (some cohorts via IBM).
Flexibility: Live class recordings are available for 6 months post-course completion.
