What are some real-world examples of encapsulation in programming?

Encapsulation is a fundamental concept in object-oriented programming. A real-world example is a class representing a bank account, where the balance is kept private and can only be accessed or modified through public methods like deposit and withdraw.

Can you give me another example?

Sure! Consider a car class. The internal workings of the engine are encapsulated, and users interact with the car through methods like start, stop, and accelerate, without needing to understand the engine's complexity.

How does encapsulation improve code security?

Encapsulation improves code security by restricting direct access to an object's data. This prevents unauthorized modifications and helps maintain the integrity of the data.

Are there any downsides to using encapsulation?

One downside is that it can lead to increased complexity in code, as developers need to create additional methods to access or modify data, which can make the code harder to read.
