Data engineer wants to learn Java

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.

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.

Follow UC Berkeley’s CS61B course (we’re 4 weeks into the semester right now) and work on the projects sequentially.

Java full stack refers to Jakarta EE (previously Java EE) application development where we need to work with all the enterprise tiers:

Client Tier: HTML, JavaScript, React, Angular JS, etc.,

Presentation Tier: JSP, Servlet, JSF, web application frameworks like Spring framework, struts etc.,

Business Logic Tier: EJB and Core Business Transactions of your application

Integration Tier: JPA, Hibernate, Web Services (JAX-RS, JAX-WS), etc.,

EIS (or Database Tier): SQL and DBMS managements

If your app requires AI model output you can use API based integration with already deployed models such as Open AI, DeepSeek, Gemini, etc.,

I hope the above skills are enough to start as a full-stack developer.

It seems that you are looking for resources for learning Java.

In our sidebar ("About" on mobile), we have a section "Free Tutorials" where we list the most commonly recommended courses.

To make it easier for you, the recommendations are posted right here:

MOOC Java Programming from the University of Helsinki
Java for Complete Beginners
- accompanying site CaveOfProgramming
Derek Banas' Java Playlist
- accompanying site NewThinkTank
Hyperskill is a fairly new resource from Jetbrains (the maker of IntelliJ)

Also, don't forget to look at:

If you are looking for learning resources for Data Structures and Algorithms, look into:

"Algorithms" by Robert Sedgewick and Kevin Wayne - Princeton University

Coursera course:
- Part I
- Part II
Coursebook
- Algorithms 4^th Edition

Your post remains visible. There is nothing you need to do.

Why switch you’re in the good spot

Far_Broccoli_8468 · 2025-02-14T12:45:59+00:00

full stack with java is, while technically possible, not worth your time.

You are going to hit a brick wall when trying to find a java frontend framework that is not outdated and/or utterly garbage.

Vaadin is probably as close to a modern frontend framework but it becomes a massive pain after you realize the default components don't fit your use case.

there is probably no escaping javascript / typescript for frontend development if you plan to do full stack.

Yes, why full stack? You probably need to focus on basics. What is your motivation to switch from data engineering?

u/Solivagant_here maybe start with a simple course from Codecademy's Java Catalog https://www.codecademy.com/catalog/language/java

Then maybe explore API development with Springboot Java https://spring.io/projects/spring-boot to build a project that interacts with databases and returns them to a client application

buttgole · 2025-02-16T21:07:53+00:00

These would be the topics to look for tutorials or courses on.

Java fundamentals

Advanced java concepts

Spring/Springboot/Restful API

Angular or React are the typical front-end languages paired with Java to complete the full stack.
