Question

one sentance for each

Answer 1

1. Banking System: In a banking application, customer account details (like balance, account number, and holder's name) are encapsulated within an Account class, allowing access and modification only through methods like deposit and withdraw, thus preventing unauthorized changes and ensuring data integrity.

2. Car Control Interface: In a smart vehicle, the engine's throttle and brakes are encapsulated within an Engine class that controls how these components interact, enabling the driver to accelerate or stop without needing to understand the complex workings of the engine, thereby enhancing safety and usability.

3. Social Media User Profiles: On a social media platform, user profile information (such as username, password, and privacy settings) is encapsulated in a UserProfile class, allowing users to update their settings through controlled methods while protecting sensitive data from direct access or manipulation by external modules, thereby improving security.
