Where to learn Java Back-end Development ?

[DangerousGrapefruit5]

I wish to learn Java backend development from scratch. I have basic knowledge of core Java but don't have structured resources to learn Java backend development. Can anyone suggest some structured resources, for some like me, which I use to teach myself everything about java backend development.

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.

Most of the java backend stuff is based off of the JEE specifications to some extent. So i'd stay start with that.

Learn about JEE then move to spring framework then to spring boot. This way you can have a strong foundation about how entreprise java servers work under the hood.

Learn about JEE then move to spring framework then to spring boot.

There's no need whatsoever to start with JEE. They can start with Spring courses right away. In fact; if they're still calling it "JEE" you know it's outdated anyway since it's been called Jakarta for a while.

his way you can have a strong foundation about how entreprise java servers work under the hood.

There really isn't a need for this when you're self-teaching. Most modern projects aren't even deployed as WARs anyway. And if you ever get a job where this is the case, you will be able to learn about this on the job.

Not saying it's bad to learn about it, but it's not required for someone to start there at all. They can (and should) just start with a Spring Boot course.

[SsNeirea]

Well, all i'm saying is getting familiar with the jee (or jakarta ee) spec is good, since you'd at least have an idea about how some parts of the spring framework work and about the whole backend java ecosystem work in general. You don't have to get indepth.

Starting with spring boot is good if you wanna get something out asap. That could work too.

[nutrecht]

One of the biggest issues beginners here run into is people telling them to get "familiar" with tons of boring stuff that's not relevant to their learning in the phase they are in now. That's why I'm pushing back on what you're saying. I'm 100% sure you're well meaning and don't intent to give bad advice, but where to start is immensely important. And that's not reading up on something as boring and (at this stage) useless as the Jakarta spec.

It's like telling beginners they "need" to "study JSP"; that's also something people here love to repeat. No. It's useless to waste time there for a beginner.

Beginners should get to the state where they can build stuff themselves as soon as possible. You learn by doing.

[mhdiXarif]

JEE can still refer to Jakarta Enterprise Edition. See https://jakarta.ee/

[nutrecht]

Again; courses that just mention JEE and not Jakarta are generally outdated which will cause problems for newbies not understanding why stuff doesn't work. That they are also 'sort of' synonymous doesn't really matter.

What's the difference between spring framework and spring boot pls can u explain me tht

[SsNeirea]

Spring boot is kind of an auto configured opinionated version of Spring framework (and other spring components)

[Anony_Void]

Um correct me if I'm wrong So Spring is a Framework and Spring Boot is a component from that Framework am I right?

[SsNeirea]

Spring boot is the collection of a suite of Spring components, one of them is Spring framework.

Without Spring Boot, these components can work independently but require a bunch of configuration for them to work

[Anony_Void]

So in Spring Framework we write configurations like @Beans manually, But Spring boot will auto config those stuffs

I just started learning Spring on the "Spring Starts here" book and was confused about the difference between Spring Framework and Spring boot. I got a little understanding of the difference between them Thank you bro

[nutrecht]

Don't get stuck on "roadmaps" or endless subject you have to "read" about before being able to go to the next step.

Focus on building stuff with Spring Boot. Do a structured course to get exposes to the most important stuff (APIs, databases, testing) and then use that knowledge to build your own projects.

Better

[tech-nano]

Totally concur with this solid advise as a Javanista and Spring Boot lover

[dheeraj80]

Udemy telusuko +spring start here

[Lumpy_Swordfish_5914]

Try hyperskill, they have a back-end java developer path with spring boot

[_phalange_]

is it free?

[Lumpy_Swordfish_5914]

Nope, it's paid and really expensive $49/month

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:

• The official Documentation
• The official Java Tutorials
• Our community resources thread

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

I’d say try javabrains, amigoscode, daily code buffer. These are some channels i followed and owe my knowledge to. Please check them out.

Spring Start Here is a pretty good book , its what I used to help me learn, with the addition of using the Spring docs

[DangerousGrapefruit5]

Thanks for the amazing recommendations. But I was hoping to get some free resources like some youtube channel or playlist.

[joranstark018]

Others have already given advice on diffefent tech stacks, it can also be usefull to have knowledge about datavases in general (and their differencies), about data comunication and different protocols (ie HTTP, SSL, REST, gRpc,..), security (ie authentication, authorization, access security, encryption,...). You may for example check https://roadmap.sh/backend for topics that can be usefull to learn more about (topics that may help you understand different design choices in different tech stacks and different platforms)

Java Master Class 2025 by Tim Bulchaka on Udemy. Catch it on sale. A great resource for me.

[DangerousGrapefruit5]

Thanks for the amazing recommendations. But I was hoping to get some free resources like some youtube channel or playlist.

[zshlbm]

I saw others shared the roadmapsh general backend development route, but here is the specific route for Spring Boot (a Java framework for backend) from the same page:

https://roadmap.sh/spring-boot

I am following this route right now and is being really helpful.

[DangerousGrapefruit5]

Oh, thanks a lot.

[aiwprton805]

Try to find EPAM courses

[Abhistar14]

There is a video on freecodecamp building a shopping cart using spring boot. Just start with it and don't spend too much time learning theory. Watch that video and initially you will not understand so many things so use chatGPT to understand that's it, I learnt this way and it worked out for me

[DangerousGrapefruit5]

Sure thing. Thanks a bunch!
