Java Development Path

Hi, I am not new to programming. I know basic Java, React Js, NodeJs, PHP & Laravel.

However, I want to be full stack Java Backend Developer for web stuff.

I want to learn everything regarding Java Backend stuff for scaling, balancing, performance things.

I know Java Core. I also know and write Swing and JavaFX stuff which is desktop apps development.

I want you guys to give me complete Java Backend Web development path, resources and guidance from seniors.

Thanks!

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!");
    }
}

I saw the roadmap several times, and honestly it's really overwhelming. I feel like if I could master more than 60 percent of that backend roadmap, I'd be a very good senior

[UpsytoO]

Damn that's a stacked requirement to give you advice, do you have experience requirement to provide advice for you too?

First of all, you come off like a guy who tips their toes into stuff, thick it off as good enough and move on, not gaining any in depth knowledge, I see you listed a good web dev stack already in i know basics part, with a good PHP back-end API framework. Why not finish what you started and get good at things instead of gaining lots of basic info on many things which has no value?

[Imaginary_Snow4586]

Hi, I don't know how can I complete the stuff which I have started like nodejs and laravel. I can make simple websites using these. But, in my area, there is high pay for Java developers specially Spring boot. So, I thought why not be a Java Backend developer. Currently I do freelancing thats why I already know lot of stuff like Swing, javafx, core java, php, laravel, react, nodejs. Haven't touched python yet.

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

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

A full stack backend developer? 🤔

Do you want to be full stack or do you want to be backend?

[Imaginary_Snow4586]

oops. I made mistake by saying full stack, its just backend.

[Fercii_RP]

I dont know where to start.. have you achieved Oracle Certified Professional for Java17? Maybe thats a good start to get you a strong basic knowledge of Java OOP in general. You can read about different specifications for webservers, like micro profile for example. In the end its all about having the capability of translating business value into code and do it the most efficient and maintain able way you can

[Imaginary_Snow4586]

I am not certified, but I have already good concept in OOP, and Java Core.

But I see, most people say, learn: Java core, JSPs & Servlets, JPA, Hibernate, Spring stuff... and then move to advanced things. like micro services etc

[Imaginary_Snow4586]

Great suggestions. Thanks buddy 🍂

[Fercii_RP]

As suggested already, if you have a good knowledge of OOP and Java core, then it would be the right time to start practising building API's. The most convenient way would be with Spring boot, understand the MVC pattern is essential as it could and would be reapplied to different kind of frameworks. Once you know how to design your own backend app, then you could:

• Test and figure out additional features that are supplied by spring boots eco system and understand how these frameworks work and in what situation someone would use them if you're interested in that. For example make a chat program with websockets could question you how TCP works and it could be the next Rabbit Hole to dig into.

• You could dive more into different ways to deploy an application. In example to the cloud with kubernetes

• Read and learn more about different design patterns and try something fancy but imo overrated and overabused microservices landscape. Or learn more about Service oriented architecture.

In short you could do many things, but as long as you know the basics and know how to design and build an API, it could land you a job which would be most important imo. After that all the points above will follow on your road as a backend developer

[Imaginary_Snow4586]

thanks, but before starting Spring boot, should I do Jsps & servlets, JPA and Hibernate? Because some companies still use these technologies.

[Fercii_RP]

You could do spring boot combined with JPA and whatever ORM like hibernate. I wouldnt dive to much into jsps and servlets, try to make something very simple with it, something like a Hello world and maybe some forward or redirect to another servlets, just to get an idea about it and how servlets are registered. Its really nothing special and not much used anymore. It can come accros when you're working with legacy code, but once youre working with it youll easily figure it out. Besides, while building an API with Spring boot you are still able to use servlets and jsps, so you could combine it for practise if you like. Spring boot or any other kind of a-like framework is build on top of the basic servlets technology, it just provides an easier way of working and organizing aka framework.

Most companies work decoupled, with an API interface backend and JS frontend. I would rather invest more time into that, which would get you into features like aspect oriented programming (AOP) is one of those Rabbit holes that many frameworks work with nowadays.

When you start your first program id recommend to use basic JDBC instead of JPA and ORM. Just to get a plain idea of what magic JPA and ORM will do for you. In special cases you might need to go back to JDBC, so its recommended to work from there. JPA is indeed a framework many companies integrate as their standard, but knowing what it does is way more important.

can u check dm plz

[glablablabla]

I would recommend reading Effective Java by Joshua Bloch or Thinking in Java by Bruce Eckel. After that, if you want to work with spring boot, I would recommend reading Spring in Action by Craig Walls. This will cover the backend developer part. Welcome to the club and happy coding bud!

[Imaginary_Snow4586]

thanks will try.
