A private field is an encapsulation mechanism in object-oriented programming that restricts direct access to the field by code outside the containing class. This ensures that the internal state of an object can only be modified or retrieved through specified methods, maintaining integrity and promoting a robust design.

Private Field

Encapsulation mechanism

Object-oriented programming (OOP) is a programming paradigm centered around the concept of objects, which are instances of classes, encapsulating data and behavior together. This approach promotes code reusability, scalability, and organization through principles such as inheritance, encapsulation, polymorphism, and abstraction.

Object-oriented Programming

Direct access refers to the ability to retrieve or manipulate data in a system without intermediate steps or processes, allowing for efficient and immediate interaction with the data. This concept is crucial in computing and data management, where it enhances performance by enabling faster data retrieval and processing.
