Object-Oriented Programming Concepts

Encapsulation is a core concept in object-oriented programming: it bundles an object's attributes and behavior into a class. Classes typically hide their implementation details from client code—that is the idea behind encapsulation. For example, when using a computer, a user only needs to press keys on the keyboard to perform certain tasks; they do not need to know how the computer works internally. Even if they happen to understand its inner workings, using the computer does not depend entirely on those details.   Create separate classes to encapsulate different functionality, then call them from a main class to perform different tasks.
