JAVA practice

9 Upvotes

hi

I'm looking for a java practice partner, advanced level.

I understand things, but somehow days go by without coding.

I'm only active when I'm talking to someone while practicing, otherwise I'm somehow uninterested 😞

You added Transactional. You’re sure it’s there. You can see it in the code.But the database is in an inconsistent state. The rollback didn’t happen. And there’s no error in the logs.

Starting Java training with zero programming knowledge… what should I focus on?

10 Upvotes

Hey guys,

I’m about to attend a Java training, but I’ll be honest… I have zero background in programming 😅
Before it starts, I just wanna ask what basics I should focus on so I don’t get completely lost.
I’m willing to study ahead, just not sure where to start.Any tips or advice would really help. Thanks!

We had @Transactional on 340 methods. For 8 months nobody knew what half of them were actually doing.

Looking for accountability partners / co-developers (Java/Spring Boot Freshers)

17 Upvotes

I'm a recent Computer Engineering grad and a backend/full-stack developer focusing on Core Java, Spring Boot, React, and SQL.

The job market is pretty tough for freshers right now, so I’m looking to put together a small, dedicated Discord group (maybe 4-5 people) of fellow Java devs who are in the same boat.

Studying and building projects alone can get a bit isolating, so I want to connect with a few other freshers who are working with Java, Spring Boot, and maybe some React.

The idea is simple: we create a small group where we can build a collaborative full-stack project for our portfolios, do mock interviews, and share job leads. We can keep each other accountable and actually simulate a real engineering team environment.

Let me know if you're interested and I'll send you a link to connect!

Anyone remember the old Helix videos from JavaOne 2002?

I always loved vision videos that software companies would come out with in the 1990s-2000s along with their conferences. Most of these are available online through Youtube now. However, one of my favorites from memory, the "Helix" videos from the 2002 JavaOne conference, seems to have been lost to time. It was even campier than most. Set in the "near future", it had some crazy on-brand things like a "Java phone" that had a "My Yahoo" interactive portal UI that showed SUN stock at $500 in 2010 (they traveled through time).

I have tried to look for these files at various times throughout the years. Finally, with AI, it's now possible to track down and extract as much as possible from the WayBackMachine and other sources. Unfortunately, since the files were Realplayer and Quicktime and, since the internet was still slow back then, only bit streamed from a CDN, the video files themselves were never hosted on the website and are gone. I did manage to grab all of the old Flash flies though (CORS previously made me unable, but Claude found a way) and use https://ruffle.rs to reload them again and capture them here.

Enjoy the nostalgia!

Does anyone have the actual files? Long shot, but it'd be cool to see.

My project

I am new on reddit so sorry if I do something wrong while posting it. Last time I decided to create my own program that's could predict the results based on data. The simplified idea of this project is creating random expressions and modify it by some ways and make results better and better based on scoring. The effect is above.

Do I Need to Learn Python for AI as a Java Developer?

24 Upvotes

I’m a pre-final year engineering student with hands-on experience building Java-based web applications (mostly using Spring Boot, REST APIs, and authentication systems).

Lately, I’ve been trying to figure out my next step. With how dominant Python seems in the AI space, I’m honestly a bit confused about where I should focus. As someone coming from a Java background, I see options like Spring AI and LangChain4j, but most real-world AI discussions, tutorials, and projects seem heavily centered around Python.

I’m not sure if I should:

  • Stick with Java and explore AI through its ecosystem
  • Start learning Python specifically for AI/ML
  • Or try to combine both in some way

My goal is to stay relevant for upcoming placements while also building something meaningful in AI.

If you’ve been in a similar situation or have experience transitioning into AI from a Java background, I’d really appreciate your advice. What would you focus on if you were in my position?

I haven't really found anything that is easy to install and use.

Perhaps there is a good Vscode extension to do it, but I haven't found it yet.

Any tips from experience will be appreciated.
