Which programming paradigm do you primarily prefer to use in Java projects?
A) Pure object-oriented (heavily focused on classes and inheritance)
B) Functional approaches (lambdas, streams) as the main focus
C) Hybrid, combining both OOP and functional features
Why did you choose this approach? Do factors like performance, code readability, or team habits influence your decision? What are your thoughts and experiences on this?

Dude, last year when we were designing a microservice, we went for a fully hybrid approach. At first, we built our domain model with classic OOP, shaping the classes with inheritance hierarchies so most of the team could move forward comfortably, saying, "The objects are already related anyway." But when we hit the data processing part—especially filtering and transforming large JSON lists—our code turned into a mess unless we brought in lambdas and streams. Once, we had a dataset with 1M records, but we only wanted the active ones. When we used a "filter" + "map" combo with streams, the line count dropped by half, and performance improved by 30-40%.
I think the best outcome came from keeping OOP’s solid architecture intact while plugging in functional tools at the "critical" points. Once the team saw both methods working together, code readability went up. Even new devs could pick up streams right after understanding the classes. In the end, the paradigm we chose was hybrid because it gave us a maintainable structure *and* let us process data flows efficiently.
