Deliverable: A Java application with separated model, service and repository layers demonstrating interface use and encapsulation, with JUnit tests covering the service layer.
Course
Full Stack Java
The stack large Indian enterprises and services firms actually run — Java and Spring Boot on the server, React on the client, with a relational database designed properly underneath.

Projects you will build
Secured Spring Boot API
Deliverable: A documented REST API with JPA persistence, validation, consistent error responses and role-based security, covered by integration tests running against a real database in CI.
Full stack application
Deliverable: A React front end consuming your Spring Boot API, deployed with a managed database, with an architecture note explaining the API contract and where validation is duplicated and why.
Team feature with code review
Deliverable: A feature built in a two-person team using branches and pull requests, with at least four substantive reviews given and received, and a retrospective on what review caught.

Placement assistance
Every student gets placement assistance — that is what 100% placement assistance means. It is support for all, not a job for all. We do not promise a specific salary, a specific number of interviews, or placement at any named company, and you should be wary of anyone who does.
What is included
- A place in the monthly placement drive, held every third Saturday
- The readiness programme every second Saturday — mock interviews and preparation
- CV review against the specific roles you are targeting
- Portfolio review, so your project work is presented the way a reviewer will read it
- Access to the vacancy pool employers send directly to the Samyak network
- Guidance on which roles realistically fit your background and which do not
- A place in the next drive, with coaching, if you are not selected in this one
What is not included
- Any guarantee of a job, an interview, or a particular salary
- Placement at a named or partner company
- Applying to jobs on your behalf
- Support before you have completed the course and its project work
- Visa, relocation or overseas placement assistance
Why this stack, in this market
Java full stack is unfashionable in the places that talk loudest about technology, and it is where a very large share of Indian entry-level hiring actually happens.
Banks, insurers, telecoms and the large services firms staffing them run on Java, and they hire in volume with structured training programmes. If your realistic target is one of those employers — and for many graduates it is the most achievable one — this stack is the direct route.
That is a market observation rather than a technical claim. MERN is a fine choice too, and our course page for it makes its own case.
Eight months, and why we do not compress it
MERN takes six. This takes eight, because there is genuinely more.
Java is more verbose than JavaScript, so the same functionality takes longer to write and read. The enterprise stack has more distinct pieces — Spring, JPA, Maven, Spring Security — and each is worth understanding rather than configuring by copying from a tutorial.
The courses that compress this produce developers who can generate a working API and freeze when it behaves unexpectedly, because they cannot say what Spring did on their behalf. That gap shows up immediately in interviews.
The seam is where the interviews go
Once you are past the syntax round, questions move to the boundary. Why is validation duplicated on both sides. What does the API return when a record does not exist, and why that status code. Where does authorisation get enforced. What happens if the front end and the API disagree about a date format.
The full stack projects here are built so you have made those decisions yourself and can explain them, which is a different thing from having read about them.
What we do not cover
Algorithmic problem solving to the depth product-company placement rounds demand. That is a separate body of practice, and if your target is a company with a data structures round you should plan dedicated time for it alongside this course rather than assuming it is included.
Questions
Full Stack Java — frequently asked questions
Java full stack or MERN — which should I choose?
Look at the employers you would actually apply to. Java full stack dominates large enterprises, banks, insurance and the big Indian services firms, which hire in volume at entry level and offer structured training. MERN dominates startups and product companies and is faster to become productive in because it is one language across the stack. Neither is wrong.
Why is this course eight months when MERN is six?
Because Java is more verbose and the enterprise stack has more moving parts — Spring, JPA, Maven, Spring Security — each of which is genuinely worth understanding rather than configuring by copying. Compressing it produces developers who can generate a working API and cannot explain what auto-configuration did on their behalf.
Do I need data structures practice separately for placements?
For campus and product-company placements, yes. Those interviews test algorithmic problem solving beyond what any language course covers. This course gives you the Java fluency and collections knowledge that make dedicated practice far more efficient, but it is a separate body of work and you should plan for it.
Is Spring Boot enough, or do I need to know Spring Framework?
Spring Boot for practical purposes, and it is what job postings ask for. Understanding what Boot is doing underneath — component scanning, auto-configuration, the application context — matters because that understanding is what lets you debug it. We teach the concepts rather than only the annotations.
How much React does this course cover?
Enough to build a competent front end against your own API — components, state, routing, data fetching, forms and TypeScript. It does not go as deep as our MERN course on the React ecosystem. The emphasis here is the enterprise back end, with a front end substantial enough to make the seam real.

Related courses
- Java Programming
Core Java properly, then Spring Boot — with real weight given to object-oriented design and the collections framework, because that is what enterprise Java interviews actually test.
- MERN Stack Development
One language across the whole stack, taught as a connected system — including the judgement about when a document database is the wrong choice, which most MERN courses never raise.
- SQL and Databases
SQL taught against a database big enough that a bad query is noticeably slow, because toy datasets hide performance entirely and performance is half of what the job tests.
