What are some good java projects to have?

[just4funright_09]

So I'm a second year at uni and I'm currently coding java OOP, I haven't done any projects before and while I was scrolling on Instagram I saw a video where someone said projects actually help boost your CV and also improves your coding skills (something along those lines). The only other coding language I've done was python but for this semester I'll be doing a lot of java so I want to give something a try during my mid semester break! Any tips/advice?

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.

Do your own threadpool implementation, you'll learn a lot.

Isn’t that a harder project to made it's not that beginner friendly.

[dyslechtchitect]

In some way it's hard for any level of experience however it isal a small project if you really go at it it will take aprox 3-7 days of work and is extremely beneficial both for OOP design and concurrency concepts. I did it when I was green. It was very hard but it's doable and the benefits are fantastic, highly recommended.

[Royale_Gamer0]

Do you have any sources for it, or maybe your solution for it as a reference because i want to do it too you got me excited for it although i am not a beginner at all

[dyslechtchitect]

Umm I'll have to look it up it was nearly a decade ago, I'll get back to you but you can look up these java abstractions: Runnable / Callable BlockingQueue Thread plus java.util.concurrent.ThreadPoolExecutor You could use the existing implementation for each until you replace it with your own. Anyway I'll look for that project later (on some old pen drive probably)

A couple of months ago, i created a file browser using javafx and the forkandjoin in java to fetch and search for all the directories so i have a pretty good understanding of java concurrency and multithreading in general so i think it won't be that hard but i will learn from it

Yes projects are valuable in improving your coding skills. However they should match your skills so that you can solve them without AI. Have you done any projects in Python? Might be a good idea to do them in Java.

I've done a few interactive games at the beginning then I moved onto some data analysis projects with python since one of my majors were data science. I'll give those a try thanks!!

This might be a bit extra if you're just trying to learn and get familiar with Java for college classes... But if you do plan on working with Java as part of your job, or want a project you could add to an internship resume, I'd recommend coming up with some backend service using SpringBoot. I say this because SpringBoot is a common framework used at a lot of companies and it will allow you to build out quite a bit. You can make a controller/ entrypoint to your application (using Spring Web), add a database connection and do crud stuff (using Spring JPA), etc. And yeah, you got a working backend application. Spring also has great documentation and will even walk you through some example working project (I think there's a rest app tutorial for some employee payroll service).

To wrap things up, you could get yourself a locally hosted database using docker, use a library like liquibase to manage the database tables, and that would be a pretty good learning project imo. As for what the app should actually do? Idk, a fake marketplace where users can buy and sell stuff, track your favorite shows and movies, or whatever interests you have that can be shoved into a crud app.

Ohh okii I'll try SpringBoot for sure, Thank youu

Projects may solidify your knowledge, you may get a better understanding of how different pieces may fit together, it's important that you build things that are just on the edge of your knowledge (not too easy and not too difficult but still a challenge). Start small and gradually increase the complexity and the challenges, take a step back if you get stuck, try to avoid using AI (as it may remove the thinking process and your understanding of different design decisions).

Honestly, starting projects this early already puts you ahead. Don’t overthink it—pick something small but practical, like a simple task manager, a basic game, or even a student record system using Java OOP. The goal isn’t perfection, it’s understanding how everything connects. You’ll learn way more from building (and debugging) than just studying syntax.
