Access Modifier

Abstract

---

• Keywords that define the accessibility or scope of classes, methods, and field

Good design

We should make all attributes within the class private.

Use methods to enforce access or modify attribute values if necessary, but this is generally not recommended.

private

---

• When a field or OOP Method is declared as private, it can only be accessed within the class in which it is declared. Direct access from outside the class is not allowed. This helps with maintaining the abstraction barrier

Important

Objects of the same class can access each other’s private fields and methods. Because the private access modifier restricts access at the class level, not the object level.
