What is encapsulation in Java?

Encapsulation is a fundamental concept in object-oriented programming that restricts access to certain components of an object.

Can you give me an example of encapsulation in Java?

Sure! In Java, you can use private variables and public methods to control access. For example:

class Person {
    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

Here, the name variable is private, and you can access it through the getName and setName methods.

Why is encapsulation important?

Encapsulation is important because it helps to protect the internal state of an object, reduces complexity, and increases code maintainability.

What are the benefits of using encapsulation?

The benefits include improved security, easier debugging, and the ability to change the internal implementation without affecting external code.
