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.
