What are some examples of encapsulation in C++ and Java?

Encapsulation is a fundamental concept in OOP. In C++, you can use classes to encapsulate data and methods. For example, a class Car can have private attributes like speed and fuel, and public methods to access and modify these attributes.

Can you show me a code example in C++?

Sure! Here's a simple C++ example:

class Car {
private:
    int speed;
    int fuel;
public:
    Car() : speed(0), fuel(100) {}
    void accelerate() { speed += 10; }
    int getSpeed() { return speed; }
};

This class encapsulates the speed and fuel attributes.

What about Java? Can you provide a similar example?

Absolutely! Here's a Java example:

class Car {
    private int speed;
    private int fuel;

    public Car() {
        speed = 0;
        fuel = 100;
    }

    public void accelerate() { speed += 10; }
    public int getSpeed() { return speed; }
}

This Java class also encapsulates the speed and fuel attributes.

What are the benefits of using encapsulation?

Encapsulation helps in data hiding, reduces complexity, and increases code maintainability. It allows you to change the internal implementation without affecting external code.
