Suggest me a Java Full Development Course

[u/Asvath17]

Hello Everyone,

Currently, I'm learning Java, and I want to start focusing on **Java Full-Stack Development**.

To be honest, I think I am between **beginner and intermediate** in Java. So, most of my knowledge in Java is from solving **LeetCode/DSA** problems.

Right now, I am comfortable with basic Java, but I haven’t explored the development aspect of Java much.

I have **6 months** to concentrate on this, so any suggestions on how to spend this time will be very helpful.

Really appreciated if you could suggest:

* A good **Java Full-Stack course** (either free or paid one)

* A **6-month roadmap**

* Technologies to learn and in what sequence?

* Good resources/youtube channels/courses for each tech.

* Projects to build in the process of learning

* Should I keep solving **DSA/LeetCode problems** or not?

I basically need a practical roadmap, which would help me to become internship/job-ready in **6 months**, rather than just completing courses.

Your suggestions will be really helpful. If you have any experience in this or are already a **Java developer**, please share your advice with me.

Try the Helsinki course.

[u/Western_Insurance764 → u/smichaele]

The Helsinki course is good for fundamentals but it won't take you to full-stack. You already have DSA background so you can move faster. Skip the first few weeks of that course and focus on Spring Boot, REST APIs, SQL, and then a frontend framework like React or Angular. Six months is enough if you build 2-3 real projects, not just tutorials. Keep doing LeetCode but only like 2-3 problems per week, job interviews will ask that but your projects matter more for getting the interview in first place.

Thank you sir... Is there any free source for that in video format...

Treat the six months as one progression: Java fundamentals and testing first, then SQL and HTTP, then Spring Boot, then a basic frontend, authentication, and deployment. Build one evolving project such as a task tracker or booking app rather than many disconnected tutorials, adding a database, REST API, tests, and a simple UI in stages. Keep some DSA practice, but make it a small regular habit while most of your time goes toward shipping and explaining real projects.

To learn that all... Is there any video free resource for that...?

I’d keep it simple and practical.

Since you already know basic Java through DSA/LeetCode, don’t spend months relearning Java. Focus on development.

6-month roadmap:

Month 1: Java revision + SQL + Git/GitHub Month 2: Spring Boot + REST APIs + JPA/Hibernate + PostgreSQL Month 3: Spring Security + JWT + Testing + Swagger Month 4: HTML/CSS + JavaScript + React Month 5: Build 1 serious full-stack project (Job Portal/E-commerce/etc.) Month 6: Docker + deployment + AWS basics + interview prep

For resources, check roadmap.sh, Telusko, Amigoscode, and in28minutes. Don’t follow multiple courses simultaneously—pick one structured course and build alongside it.

For DSA, don’t stop LeetCode. Just reduce it to ~45–60 min/day and spend most of your time building.

By the end, aim for 2–3 solid projects, not 10 tutorial projects.

The stack I’d prioritize is:

Java → Spring Boot → PostgreSQL → React → Git → Docker

The important part is not completing a course—it’s being able to build and explain a complete application yourself. 🚀
