Is there demand for junior Java developers in Poland in 2026?

Yes, stable demand. Java dominates Polish banks, fintech, telecom, and enterprise. Fewer junior offers than Python but a more stable long-term career.

Java vs Python: which is better for a beginner in Poland?

Java — enterprise stability, banks, long-term career. Python — faster start, AI/ML, higher junior pay. Pick Java if you target fintech/banking.

How much does a Java developer junior earn in Poland in 2026?

Junior Java: ~PLN 8,500 gross (UoP) or 8,000–12,000 net (B2B). Mid (after 1–2 years): PLN 16,750. Top rates in Polish banks and fintech.

Spring vs Spring Boot: what is the difference for a junior Java?

Spring — base framework with modules, needs manual config. Spring Boot — wrapper with auto-config for a fast start. Junior should know both, focus on Boot.

Do I need a technical degree for the Java course at Mate academy?

Topic:Education

Answer:

No, but analytical backgrounds help. Java is harder than Python due to strict typing and Spring magic. Switchers from non-tech industries may need more time.

A technical degree is not required, but Java is less beginner-friendly than Python because of: a more extensive syntax, strict typing, and a large set of enterprise concepts (IoC, DI, AOP, Spring "magic"). Switchers from humanities may need more time to adapt (typically 7–9 months instead of 5–6). Recommendations before starting: understanding OOP (at least theoretically), basic programming logic (variables, loops, conditions), B1+ English. If you are unsure — start with Python or Frontend, which have a lower entry bar. After a year of work you can move into Java. 90% of our Java students started without a tech background — the key is readiness to study systematically, not innate ability (source: Mate academy data 2026).

Thanks to Mate academy, after a previous unsuccessful attempt to enter the IT industry, I managed to find a job within 30 days of completing the course. A wealth of knowledge, support from mentors and assistance in conducting recruitment interviews are three of the many advantages that Mate academy offers on a new career path

What can I say about Mate academy? Theoretical and practical preparation at the highest level. But in my opinion, this is not the main advantage of this course - the advantage of this course are mentors who are convinced of your success and support you at every stage of your activity. Through learning practice, understanding theory, practicing soft skills, support in job search and related aspects.

I recommend this course to people who want to enter the world of IT and don't know where to start. There is a lot of knowledge on the Internet, which is beneficial, but at the same time it can be confusing for a beginner. At Mate, you get a defined learning path waiting for the motivated student. Additionally, the help of mentors, test tasks and code reviews drive development and allow you to get your first job.
