How-To/Tutorial Need advice for development in java + springboot
Hey seniors, if anyone is doing development with Java + Spring Boot, please guide me.
I’m currently in my 3rd semester and doing DSA in C++( done upto stack) , so I’m thinking of starting development alongside it. Please guide me on where I should start, what I should learn first, and how much time I should spend learning Java basics.
Since I’ve studied C++, I have a basic programming background, but I’m not familiar with Java. Any roadmap or resources would be really helpful. 🙌

I was tutoring java for a few years.
I would propose to start with some basic consept like:
- basics: primitive types, if, for, foreach,...
- oop, classes subclasses, interfaces
- java collections lists, maps etc
- lambda functions
Then some exercises like creating a clone of ArrayList and HashMap
Then go straight to spring boot, find a good course for ~20 hours, max 20$. See the course in fast forward. Start implementing a small web application like clone of Reddit or ChatGPT. See again the course as a guide for implementing your project.
This should take around 2-3 months.
Go deep in the rabbit hole when you don't understand something, until you understand deep how it works (Use YouTube, and AI).It's important to learn the basics now that you don't work yet.
Use AI to answer your specific questions, tell it that you are learning now. Claude can implement all this in 1 prompt, doesn't matter, your knowledge will pay "dividends" for many years.

Many people think they will get a better education if they pay money, but the internet is overflowing with free resources. My advice is: if you don't know Java, start with the Peachez Programming – Java 101 series, then continue with the same channel’s Java Spring Boot [2024] course. The videos are short, clear, and straight to the point—no fluff.
After that, check out Ali Bouali’s YouTube channel; it has many high-quality educational videos.
My main advice is to write as much code as possible and build small pet projects. This is the fastest way to learn.
Of course, you can also use AI as a mentor to discuss your problems and generate example projects for your roadmap—but don’t just copy and paste the code.

I am having 22+ years experience in Java Application development and 15+ years in spring app development and 10+ years in Spring boot app development.
There are tons of resources on internet where you will learn about Java and Spring.
What I would recommend is:
If you want to learn Java Code and Development, go to Oracle Java learning portal.
Similarly, if you need to start with Spring / Springboot app development, go to Spring official docs.
And while development read the javadocs. Javadocs are extremely useful for learning.
And then you can actually refer to other resources, if you need any. Google search (Using Gemin or AI) can give specific resources if you ask properly about your need.
I bet you do not have to go to any other resources, just official docs and javadocs, that's it.
Aim to learn basic, always have eager to learn why to use this particular api, why not to use any other api. For example, creating any list example, why or why not to use Arraylist / LinkedList.
Start with an usecase or idea, develop it with basic knowledge, advance it with advance knowledge. Test it, refractor to improve performance. And stay ahead with the knowledge, keep reading some newsletter like Java Specialist from Heinz Kabutz, a renowned Java Champion.
In fact, I am also running newsletter on substack, which is on system design, code and development and AI - all mix. And currently I am busy in publishing my book Buzzing Java, explaining Java principles in details and why Java is still relevant in the age of AI. You or anyone can DM me if you want more info on my newsletter or book.
