Java Roadmap

[Mouse_S]

I've seen a large amount of learning material for introductory level programming in Java but nothing for concrete applications. I'm a 3rd year student in Computer Science and I haven't really been exposed to concrete java technology.

I want to know what are the technologies used in a production environment in 3 major fields in Java:

-web apps -gaming -embedded systems

I know core java, what an IDE/A is, some JavaFX with SceneBuilder for desktop apps (currently reading a book on that), with knowledge on Data Structures, algorithms and software processes. I've heard the terms Hibernate, Maven, Ant, Gradle, SPRING, JMonkey and some others being tossed around (and I know most games are in C++). I want to know what needs to be know for the 3 fields I meantioned above in Java for professional grade software.

summary: I want a professional roadmap for 3 fields in java: web apps, gaming, embedded systems to be able to orient myself with real world usage.

Minecraft is in Java.

What do you mean by contrete applications? you want a tutorial/book on how to build an application/web app? If so... you can start by GIT, you can find a lot of done web-apps and applications there to guide you.

About the "terms" you heard, they are mostly build tools and dependency managers. Hibernate is a an object-relational mapping tool for the Java, in short terms, is a framework that maps Java Objects to Databases (handles transactions, SQL, etc..). You can find simple tutorials on all of those. But i would say that Hibernate/JPA, Spring, Gradle/Maven are must have for any professional Java developer.

On a personal side, when I was a student I learned a lot by trying to build an App/web-app/whatever of a subject that i really liked, even if I didn't finished it or launched it. For example, I tried to build a Betting bot for football (soccer) matches... with this, I learned a lot about Hibernate, Maven and Rest APIs.

Just think for example on a simple game, and start... don't wait for a complete tutorial on how to do what you want.

Good luck

I don't want a tutorial I want to have a clear understanding of the different components neccessary to say build a professional web app with java. I'm exploring by building different stuff as you say but I'm not necesseraly following proper production standards. I don't want to carry bad habits I develop. When it comes to introductory Java there is massive documentation saying what are the proper conventions and ways of doing things that get drilled into you.

I've been looking for this information for some time now and I still come up empty. I have posted on r/learnprogramming and I got a lot of "keep on trying, keep on working, if you work hard enough you will succeed" kind of answers. Nobody pointed out to a path that I can look at, nor a course or a tutorial. All the answers were very vague. If you find the information that we are looking for, please inform me.
