Can fields be made public directly?

Short answer: Technically yes, but not recommended. Makes the data vulnerable to invalid modifications. Encapsulation recommends private fields + public properties.

Real-world example (ShopNest)

Think of ShopNest’s Product, Cart, and Order classes: each object holds data + behavior, so pricing rules stay next to the data they use.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
