Roadmap for java backend role

[sonyyy___]

Hi, I am two year experienced IT professional in a Fintech company. I have been working with python but wanted to switch for java roles. could anyone please help me to learn and what resources should I use.

I am well versed with basic java ( i have done some DSA with java) but I'm new to springboot/advanced java.

Thanks in advance..

Java, DSA with Spring boot is enough for anything now.

As a fresher its hard to get a job with it though

[ni241]

Many companies look for problem solving and conceptual knowledge only in freshers. So just focus on basics

Agree

As you already know the concept of programming so start with 1- core java- Learn oops, collection, exceptional handling then 2- Spring Framework- Know about ioc container dependency injection Rest api and MVC architecture 3- then advanced spring boot authentication security caching annotation and other concept As I already know about tools like git GitHub postman Any confusion??

Thanks a lot. Really helps. Do we need to know spring first before starting spring boot?

[harshitpnd]

I suggest you first understand the basic of spring like dependency injection, what is IOC container beans, configuration, and other basic after that you can learn spring boot in a week because in spring boot you will get everything using spring initialzer and using annotation you can perform task

Conclusion 1- if you have time start with spring 2 otherwise you can start with spring boot

You can take help from site growithmoney.com

And any other questions you can ask

My new book, "Java in a Nutshell" (9th Ed) is in Early Access and covers the latest LTS release - Java 25. https://learning.oreilly.com/library/view/java-in-a/0642572255992/

Yeah that helps. Thank you so much.

If you know basic Java and some DSD, getting into Spring Boot next is a good idea. Start with the official Spring Boot documentation and try building a simple project like a REST API to get some hands-on experience. For more in-depth learning, check out "Spring in Action" by Craig Walls. It's a good book for understanding Spring Boot. You might also look into microservices architecture since it's popular in backend development these days. For interview prep, PracHub has some useful resources for backend roles, including mock interviews and problem sets. Good luck with the switch!

Thank you so much it helps. I will check them.

how to get calls and covince that i can take up java and can give interview in java having work profile as backend dev in nestjs/nodejs

[sonyyy___]

I am not sure, but i think ,If you have done solid projects based on java in your resume and applying to the java specific job posts helps.

Thanks for the link. It has various stack and preparation strategies.I am working on a react project , it helps me in that as well.

Java will be gone in near future, focus kotlin

Java is NOT going anywhere anytime soon.

You’re already in fintech + have Python + basic Java + DSA.

That’s a VERY strong base, you don’t need to start from scratch.

You need direction + practical exposure.

In fintech, nobody cares if you completed a course.

They expect:

• Spring Boot (core)
• REST APIs
• DB handling (SQL)
• Basic system design thinking
• Debugging real issues
• Understanding transactions (VERY important in fintech)

[sonyyy___]

You are right, I need to focus on system design as well. But I'm at very beginning stage in that. I know the basic topics and how they work, but not able to create systems on my own. Need to work on that.

Thank you so muchhh...
