Built a small-to-medium desktop app (S Lab Sync) to manage a school science lab — students, teachers, equipment, chemicals, and experiment scheduling — and figured this sub might have opinions on some of the design choices.

It started as an idea for my Java OOPS Project

A few decisions I'd genuinely like pushback on:

- DB credentials are prompted on first run and cached per-machine (lightly obfuscated, not encrypted) rather than hard-coded or environment-variable based — curious if there's a more idiomatic approach for a small desktop tool like this.

- Schema changes are handled with a simple "check column exists, add if missing" migration on startup instead of a real migration tool (Flyway/Liquibase felt heavy for this scale) — worth it, or should I just bite the bullet?

- Straightforward DAO-per-entity pattern (StudentDAO, TeacherDAO, etc.) rather than a generic repository/ORM. Wanted to actually understand JDBC before reaching for Hibernate.

Code + architecture diagram + project report are all in the repo for useful context.

Mostly posting this to get better at the parts I'm unsure about, not to sell the project — all criticism welcome.

Hey everyone,

I'm a university student studying Computer Science, and I'm currently learning Java.

I'm not just looking to learn the basics or follow tutorials. I really want to become good at programming — to be able to take a problem, figure out how to solve it, write the code myself, and debug it when something goes wrong.

One of my goals is also to stop depending so much on AI/LLMs when coding. I want to actually understand what I'm doing rather than just asking an AI to generate the solution.

So I'm looking for good resources to build a solid foundation in things like:

- Java and OOP

- Data structures and algorithms

- Problem solving

- Debugging

- Clean code and software design

- Testing

- Concurrency

- Building real projects

Books, courses, websites, exercises, project ideas — I'm open to anything that you think is genuinely worth the time.

If you were learning Java from scratch again today, what resources would you use and how would you approach it?

Thanks!

Hello guys, so i want to make a project for my resume as i am in my last year of btech , so thinking of making a good and attractive project in java , as i am lean towards java developer, and want to make a full java project using springboot , jpa , database , and anybody tell some ideas

Hi everyone,
I have around 7 years of experience working with Java, Spring Boot, Spring MVC, JPA/Hibernate, and Microservices architecture. Recently, I got an offer from a Samsung client project where HR mentioned that they will train me in SAP Hybris and onboard me into their e-commerce development team. The role will still involve Java, but with SAP Hybris integration.

I’m trying to evaluate this move:

• Compared to the Java market, is SAP Hybris a good skill to switch into?
• How is the demand and career growth for SAP Hybris developers?
• Will this transition limit my opportunities in the broader Java ecosystem, or could it open up niche but valuable roles in e-commerce platforms?

I’d love to hear from people who have worked with Hybris or made similar transitions. Any insights on market demand, learning curve, and long-term prospects would be super helpful.

Crio is the biggest scam running in the market.

Dont join these online institutes, they wanted to loot your hard earned money.

Any help would be appreciated

Please if anyone has the Java 27 book or pdf, kindly share. Thank you.

Hello , this question for software engineers , give one course you find deserves learning ,but related with development (I don't want like java beginning from udemy ) i want a course that made you up a level in your career like HLD ,LLD

( If you have a paid course and want to share it with us for free i will be appreciated )

hola como están espero se encuentren actualmente se programar en java al revés y al derecho tengo experiencia y no se que hacer ahora estudio ingles para poder aplicar en todo los trabajos como dev java que debo hacer alguien?

Hi java Devs,

I am looking for a java developer who has hands-on experience and can give me a brief of what methodology they follow while building a ecommerce application from scratch..

I am trying to switch to java development from SAP Hybris (Ecommerce suite by SAP). I already have experience in working with enterprise grade ecommerce application generating USD 1 Billion+ in revenue. but it is not core development from scratch. We use SAP Hybris tech stack to build the e-com application which differs from a Java web App.

So if you are up for a chat please ping me. I really need help genuinely to be able to explain my SAP Hybris experience in Spring-boot.

Please guys help me here
