What does "encapsulation" mean in programming?
encapsulation is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
The principle of bundling data and the methods that operate on it within a class, and restricting direct access to some of the class's components. Encapsulation hides internal complexity and exposes only what is needed.
Example
"Encapsulation means the balance property is private and can only be changed via the deposit() or withdraw() methods."
