Hey folks! I've been a Delphi developer for over 3 years, focusing on maintaining a legacy ERP system. It's been quite the journey with old code, numerous business rules, and minimal documentation. Lately, I've been thinking about making a switch back to Java, which is actually the first programming language I learned. I've dabbled in Java again by building APIs with Spring Boot, but I feel a bit out of practice. My game plan includes getting back into Java (especially backend with Spring Boot), working on personal projects, creating a GitHub portfolio, sharing my progress on LinkedIn, and eventually applying for junior/mid-level positions. I would love to hear from anyone who's transitioned to Java from another technology stack: Does building a portfolio really help? How do companies view non-Java devs? What should I focus on to secure a Java backend role? Any pitfalls to watch out for? Thanks in advance for your insights!

I made the switch from Delphi to Java back in '97, and I found it pretty smooth since the object model in Delphi is quite similar to Java's. Focus on learning a bit every day rather than cramming. Here are some tips that helped me:
- Create a comparison table of the languages to get familiar with their idioms.
- Use IntelliJ and learn the shortcuts; it's great for coding even if it's not as RAD-friendly as Delphi.
- Master Java streams for clearer code and take time to understand debugging them.
- Start with core Spring and experiment with simple projects, it helps you grasp Dependency Injection better.
- Write a simple REST API to get hands-on experience with Spring Web MVC and interact with it through tools like Postman.
- Don't forget to learn Hibernate and JPA, especially with Spring Data JPA and PostgreSQL for smoother data handling.
Great insights! I’d like to add that if you’re feeling rusty, jumping into some real projects can boost your confidence and skills! Stick with it!
Your plan looks solid! For your GitHub, make sure each project has a clear README because that's what most reviewers will glance at first. And consider having a mobile-friendly website for people to try out your projects easily. I also think you might be well-equipped for mid-level positions given your experience, so don’t shy away from applying to those.
Thanks for the encouragement! I’ll definitely prioritize my README files and think about creating a mobile-friendly site. Cheers for the tip about aiming for mid-level roles!
Absolutely! Just make sure your GitHub profile stands out, and don’t hesitate to aim high!
Keep in mind that there’s always a demand for developers who can maintain legacy systems like Delphi. Just don’t let that stop you from pursuing new languages like Java if that’s what interests you!
Absolutely! I appreciate the perspective. While I understand the value of sticking to Delphi, I’m really excited about diving back into Java!
It's good to have options, but always follow what you're most passionate about!
Thanks a ton for the detailed advice! It's reassuring to know that the transition can feel natural. The tips about understanding DI and writing a REST API sound like great practical steps. I really appreciate the time you took to share this!
