Ask HN: How do I know if OOP is what I need?
3 by culopatin | 2 comments on Hacker News.
I am a beginner and I'm building an application that stores DNA sequences in a SQL database. I've been using Java because I'd like to have it in my portfolio to make a lateral move in my company. The material I've been using to learn Java teaches OOP concepts, of which I barely grasp thinking in terms of objects and classes. Is this still the preferred way of thinking or in 2021 there is a better model to follow? Thanks
