What is an example of encapsulation in C++ and Java?

Can you explain encapsulation in C++ and Java with examples?

Sure! Encapsulation is a fundamental concept in object-oriented programming that restricts access to certain components. In C++, you can use access specifiers like private, protected, and public to control access. For example, a class can have private variables that can only be accessed through public methods.

Can you give me a specific code example in both C++ and Java?

Absolutely! Here's a simple example:

In C++:

class Car {
private:
    int speed;
public:
    void setSpeed(int s) { speed = s; }
    int getSpeed() { return speed; }
};

In Java:

class Car {
    private int speed;
    public void setSpeed(int s) { speed = s; }
    public int getSpeed() { return speed; }
}

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 the external interface.
