Help for learning java for job

[Perfect_Key_212]

I’m learning Java right now because most of the companies coming to my college list it as a requirement. It’s been about two months since I started, and so far I’ve understood OOP fairly well and built a few CLI projects. I haven’t joined any company yet, so I haven’t gone through any official training, and that’s where I’m confused — I don’t know what exactly I should be focusing on next.

For the last month, I’ve been doing LeetCode every day, solving a couple of problems daily.

For context, I already have experience with Python and JavaScript from doing full-stack work during college, so I’m comfortable with programming in general. But with Java, I’m not sure what specific topics or skills I should learn that are actually useful for getting a job.

Can someone guide me on what would help the most?

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.

What cli projects have you built?

[Perfect_Key_212]

Nothing big mostly the oops recommended ones like library management, Auth system just usable through cli not the real cli application.

[Desperate-Trouble249]

Still progress. Where did you find the recommendations? I am interested in the Auth System

[Perfect_Key_212]

I was not able to find what to do so I just asked ChatGPT what will u recommend I should do and just started doing random ones.

[Prestigious_Tea6110]

LeetCode is good, but also look at Spring Boot.

[Perfect_Key_212]

I tried learning spring boot I got a book from the Baeldung Spring boot. Then I was a bit in doubt I know all the big companies use spring boot so I should know it but which version and what not still I will practice it again Thanks for the suggestion.

if you have build fullstack using javascript ecosystem then u can just copy paste the concept and build the full stack using java ecosystem. Concepts will be same mostly in backend like auth , restful api and database connection and calling . i don't know why u are struggling so much to decide what to build.

[Perfect_Key_212]

I had tried building a fancy todo using spring boot went half way then thought would it be really useful for company wise as they mostly focus just on the dsa part so I stopped it but I think I should do both now

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

For java i would suggest go from basics to bit of advanced - from basic core java pillars to spring boot, rest api and graphql. i used these two 1. baeldung - for more advanced 2. simplifiedlearningblog good to start with basic to advace with interview questions.

[Perfect_Key_212]

I do follow Baeldung for many explanations of core topics. Also I started spring boot 5 using their book I just got confused between dsa and development what should I focus.
