Do you still write imperative code when working with collections that looks like it was written before Java 8? Embrace functional programming in Java. Check out my recent video about Streams: youtube.com/watch?v=pa_3nK… #java #java8 #programming #functionalprogramming

Had the chance to join the AI Summit PJATK 2025 🎉 Hosted at my school (@polskojaponska ), it was super inspiring & gave me fresh perspective on AI in business. Also… gotta say, loved the swag bag 📷 #AI #Conference #AISummit #PJATK

One day you're young, the next you're watching a Java launch stream.
Funny observation I had recently: I’ve seen more people debunking the ‘Java is dead’ claim than people actually saying it. Does anyone in 2025 still believe that Java is going away anytime soon? #Java #Programming #SoftwareDevelopment #Developers #Coding #Tech

🍃 Spring Boot Tips #4 🚀 3 ways to map inheritance with Spring Boot Data JPA: 1️⃣ Table Per Class: each class its own table, parent few fields, children many 👩🎓👨🏫 2️⃣ Joined: shared parent table, children reference by ID ✅ 3️⃣ Single Table: one table + type column ⚡

Language verbosity is a blessing in disguise. While some devs may not like it when writing a solution, you'll surely appreciate it when reading someone else's code. In non-trivial software projects, development is more about reading than writing.
🍃Spring Boot Tips #3🚀 toList() vs Collectors.toList() in Java Both produce a list from Stream, but they are not exactly the same. Collectors.toList() → returns a modifiable list ✅ toList() → returns an unmodifiable list ❌ (add/remove = UnsupportedOperationException)
My current read for this week ☕️
