Imagine a technology that’s been around for over 25 years—and is still one of the most in-demand skills in the world. That’s the reality of Java: the backbone of global banking systems, Android apps, corporate backends, and Big Data solutions. While new languages and frameworks keep emerging, Java not only holds its ground—it’s gaining new momentum.

Java by the numbers: popularity and demand

According to the TIOBE Index (May 2025), Java ranks 3rd among the most popular programming languages worldwide, right behind Python and C. Its consistent growth shows that Java isn’t fading—it’s still evolving and thriving.

In the Stack Overflow Developer Survey 2024, Java was ranked among the top languages used in corporate environments—especially in finance and enterprise sectors (Java EE, Spring). Translation? Java opens doors to stable, well-paid jobs in respected companies.

Job offers: Who’s hiring Java developers?

Let’s look at the Polish job market in May 2025:

  • Just Join IT: over 1,700 listings for Java roles
  • No Fluff Jobs: around 1,400 job posts for Java/Backend developers
  • Pracuj.pl: nearly 2,000 listings mentioning Java—most of them for mid and senior positions

These numbers prove that Java developers are consistently in demand—even during uncertain economic times.

How much can you earn as a Java developer?

Based on salary reports from Just Join IT and Bulldogjob:

  • Junior Java Developer (0–2 years): approx. 7,000–11,000 PLN gross (UoP) or 10,000–16,000 PLN (B2B)
  • Mid-level Developer: approx. 14,000–21,000 PLN (B2B)
  • Senior Java Developer: 25,000+ PLN (B2B)—and even higher at global firms like HSBC

Java lets you grow fast: after a few months of structured learning, you can apply for internships or junior roles and keep moving up.

Where is Java used? (spoiler: pretty much everywhere)

Java powers a lot more than most people think:

Banking & finance – transaction systems, risk analysis, secure applications.
Enterprise apps – large-scale corporate systems (Java EE, Spring).
Android apps – Kotlin is growing, but Java still runs behind the scenes.
Big Data, cloud, IoT & microservices – Java remains key in backend architecture.
Games and desktop apps – even Minecraft was built in Java!

Java + finance = long-term job security

In an age of automation and AI disruption, finance and banking remain some of the most stable employment sectors—and they love Java. Why?

  • These industries demand reliability, performance, and scalability.
  • Java-based systems run for decades—someone has to maintain and improve them.
  • Global players like HSBC offer career paths, mentoring, and the chance to work on international projects.

If you’re looking for a secure, high-paying, and future-proof career, Java plus an open mind toward fintech is a winning combo.

Why structured learning is key (and why Java JUMP is the perfect launchpad)
