Final-year Java developer: Should I focus on Spring Boot or system design?

[u/Old_Journalist6008]

Hi everyone! I’m a final-year B.Tech student preparing for Java backend fresher roles. I’ve been working on Core Java, DSA, and projects, and I’m confused about what to prioritize next.

Should I focus more on Spring Boot and building backend projects, or start studying system design?

For fresher interviews, how much system design is usually expected? Which Spring Boot topics should I be comfortable with before applying?

I’d appreciate advice from anyone who has recently landed a Java backend role or interviews freshers.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

Totally normal to feel torn at this stage, everyone hits that fork. But it's not really a choice: for fresher interviews, "system design" almost always means being able to explain your own project's architecture, why you chose that DB, what happens when traffic spikes. Nobody expects you to design a rate limiter for a new grad role.

Spring Boot first, no question. Get comfortable with DI, REST controllers, JPA, security, and actually deploying something so you can talk about a bug you hit in production-like setup. That's what interviewers dig into. System design reading can wait until you have a project worth designing around.

+1 on advice. In addition, Spring is less obvious before you do everything with Java the hard way. For example, using had-coded JDBC stuff in java was a glorious PITA, and then Spring made it amazingly simple. You've probably seen comments about "boilerplate"; Spring really reduces all that cruft. And building web stuff is a joy with SB.

can u please suggest me how can i learn spring and spring boot so that i could never forget core concepts

[u/Old_Journalist6008 → u/ToughCorgi4838]

Thanks for the advice! I’ve been learning Spring Boot for about a month, but I’m still confused about some concepts and how everything fits together. Could you suggest any courses, books, or YouTube playlists that would help me build a clear understanding of Spring and Spring Boot?

if you are intending on only taking backend entry positions, system design is a waste. If all things are in place, someone else will be doing the system design and your task will be to code it. Is that knowledge still great to have, yes. Ideally should you do both, yes. But if you can only do one, Spring Boot. I would say Spring and Spring boot will be the leading and most widely adopted choice.

Start with Spring principles, Springboot because pretty much noone does Spring without Springboot. Once you understand it, move to System design.

Honestly speaking if you are fresher and applied for java developer very rare chance they will ask you majorly on SD, better just focused on Spring boot in detail

how u study spring boot

[u/Outrageous_Dig2790]

System design but really you could do both

[u/sweetno]

Backend fresher roles? Focus on Spring Boot or similar frameworks. The reasoning is that system design interview rounds are usually done for higher seniority, and rarely useful for actual work. That is, there are people who do system design, but way less than you could imagine by all these FAANG interviews. And surely they won't let newbies anywhere close architectural decisions. Regarding Spring Boot: the framework accumulated quite a bit of cruft over the years, so looking into something like Quarkus to learn the concepts and general workload could be beneficial.

system design

[u/nian2326076]

Focusing on Spring Boot is a solid choice for Java backend roles, as it's widely used in the industry. Make sure you're comfortable with building RESTful APIs, dependency injection, and Spring Data JPA. System design isn't heavily emphasized for freshers, but having a basic understanding can set you apart.

If you want to practice technical interview questions, PracHub offers various resources to help you prepare effectively. Good luck!

Learn System Design if you’re already able to build a complete system. Otherwise, I’d definitely recommend starting with Spring Boot. It will help you understand how different components interact, such as databases, backend services, and the frontend, along with many other important concepts.

Once you have hands-on experience with these technologies, you’ll need to understand when to use a particular technology and why. That’s where System Design comes into the picture.

how can i learn springboot there are many courses in utube and many books exists lie "SPRING STARTS HERE" or "HANDS ON APPLICATION DEVELOPMENT USING SPRINGBOOT"

which exact path i perfer

[u/Upstairs-Ostrich-497 → u/Old_Journalist6008]

If you wanna start spring boot i recommend you to explore TELUSKO channel on YouTube, here you get a complete one shot video may be 60+ hours.... You don't have to complete it in one day or one month take your time and enjoy journey. If you need anything else feel free to ask.
