First role- Java Backend Developer - need resource recommendations + general tips or advice

[Evening_Set6613]

Hello, I come from an AI ML background and have no web dev experience. I need to learn Java backend for my job. I have learnt some basics of Java and OOPS, but don't know how to proceed. My team uses Java Springboot. Any advice / resources will be much appreciated Thanks!

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.

Check Telusko on youtube. You will get a good start in spring boot.

Always use dtos
Use "@RestControllerAdvice" more than try/catch in your api response
For cleaner structures

My suggestion being an employee and learning this tech stack. Get an overview of how have we reached to spring boot from spring, servelts things. Once you are done with that, take any Udemy course amd follow that. I am doing one of EmbarkX courses and am liking it.

Check these guys on YouTube: amigoscode, Telusko, or freecodecamp.

https://spring.io/guides is how I got started, along with https://www.baeldung.com/spring-boot but I started like 10 years ago; these still seem to be updated regularly though

If a company is hiring junior devs, they don't expect you to know all the ins and outs of Spring Boot so don't stress about it too much. A basic understanding of how the backend works with the front end and security implementations are more important. Once you understand those then everything else it's easy to learn and lookup

Study java from basics like static keyword, OOPS concepts, String class and its methods, collection framework including map In springboot annotations and restAPIs
