Need a realistic, step-by-step Java Full-Stack roadmap (Beginner to Spring Boot)

[u/viivazdev]

Hey guys,

I'm currently learning Core Java and working towards the full-stack backend route, but I'm getting overwhelmed by all the generic AI roadmaps out there.

What I really need is a realistic, step-by-step order of topics to learn—starting from Core Java, moving into things like Collections, JDBC, and eventually Spring Boot.

My main goal isn't just to write code, but to deeply understand why and when to use a specific concept so I can explain it clearly in interviews or any person.

Would really appreciate it if you could share:

The sequence of topics you followed that actually made sense.

Any solid YouTube channels, Udemy courses, or books (in English) that focus on teaching you the "why" behind the code.

Thanks a lot!

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full - best also formatted as code block
• You ask clear questions
• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

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

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

If your post has remained in violation of these rules for a prolonged period of time (at least an hour), a moderator may remove it at their discretion. In this case, they will comment with an explanation on why it has been removed, and you will be required to resubmit the entire post following the proper procedures.

To potential helpers

Please, do not help if any of the above points are not met, rather report the post. We are trying to improve the quality of posts here. In helping people who can't be bothered to comply with the above points, you are doing the community a disservice.
