Advanced Encapsulation in Java | Tell Don't Ask & Immutability | OOP Design

Описание: 🛡️ Encapsulation is NOT just about making variables private.

In this advanced deep dive, we shatter the common misconception that Encapsulation is simply about generating Getters and Setters. In fact, blindly generating them for every field leads to the Anemic Domain Model anti-pattern, effectively making your code public and fragile.

We explore professional Object-Oriented Design principles that separate junior code from senior architecture: "Tell, Don't Ask", protecting Invariants, and achieving true security through Immutability.

📝 IN THIS VIDEO, YOU WILL LEARN:

The Trap: Why standard Getters/Setters can break Encapsulation.

Anemic Domain Model: Why "Data Bags" lead to spaghetti code.

"Tell, Don't Ask": How to expose behavior instead of data.

Coupling: How proper encapsulation reduces dependencies.

Immutability: The ultimate form of encapsulation (and how to code it).
