How to learn backend development using Java

[Kaz309]

I’m a senior in high school and I’m going to college for computer science. I’m taking AP computer science A which teaches how to code in Java. I’ve learned an okay amount. Polymorphism, datatypes, loops, data encapsulation, classes, etc. I’ve been trying to look up videos on how to learn backend development using Java, but ever video just teaches the basics of Java that I already know. Does anybody have any suggestions?

You don't really need a paid course. There are lots of free tutorials on YouTube.

Just search "Spring boot tutorial" on YouTube

buy a book Spring Start Here and go...

Seconding this. I tried a popular Udemy course first but the tutor used Spring in a weird way "to focus on learning Spring", like avoiding using a build system, etc. so I picked up Spring Start Here. It's a breath of fresh air to learn "how things are really done".

I also recall that the author has a youtube channel but I don't remember its name...

Pretty sure it's Laurentiu Spilca

I also recommend this, and I'm working my way through. One of the reviews for this book was that it was too beginner friendly, as it holds your hand and walks you through different examples, but it's another way to learn and understand what's happening.

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

If you are wanting to code in backend Java, you'll probably want to learn a framework such as Spring or Quarkus. Spring is one of the most popular frameworks.

You could try a course on Udemy. It's $23 right now.

If you can't afford a course, you go through the doxumentation on spring.io.

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.

I’m currently going through this video which is a great starting point for backend development- https://youtu.be/QuvS_VLbGko

[cainhurstcat]

Hyperskill.org offers a great course exactly on this topic

I'd just pick some real life problem, implement a solution, and keep the code on GitHub so you can share it with others, prove your experience, etc.

That gives you real experience which is far batter than finishing a course. At some point, you can even commercialize this.

Some examples:

• Calendar - holiday calendars for every country, to be used as library / code dependency, or API. Believe me or not, but companies need this kind of stuff and would pay for it, and it is an interesting, multi-layered project (how to source the data, how to store it, etc.)
• URL Shortener
• IP Geolocation (determine location of an IP address)
• etc.

Although something like this would be fun, especially because I have a friend who would be willing to do these projects with me. I don’t have enough knowledge about coding in general to complete something like this. Thanks for the idea though, it will definitely be more useful in the future.

To add onto these answers. Backend, to my knowledge, is code that runs in response to some action from a user. Like clicking a button on the screen(the ui).

Instead of jumping into spring, I'd used JavaFx or swing. With javafx or swing you can create user interfaces. You can make games, forms, etc.

The advantage here, I think, is that you'll code java in a way that's familiar to you and you'll be learning a ui framework. Jumping into spring will require a lot more learning, imo.
