What are some real-world examples of encapsulation in C#?

Encapsulation in C# is about bundling data and methods that operate on that data within a single unit. A common example is a class representing a bank account. The account balance is private, and methods like Deposit and Withdraw control access to it.

Can you explain how the Deposit method works?

Sure! The Deposit method would take an amount as a parameter, check if it's valid (e.g., not negative), and then add it to the private balance field. This ensures that the balance cannot be directly modified from outside the class.

Are there other examples besides bank accounts?

Yes, another example is a car class. The car's speed can be encapsulated, with methods like Accelerate and Brake controlling how the speed changes, preventing direct access to the speed variable.

How does encapsulation improve code security?

Encapsulation improves code security by restricting direct access to an object's internal state. This prevents unintended interference and misuse, allowing for better control over how data is accessed and modified.
