Encapsulation (getter &setter)

Encapsulation means hiding data.

You keep the data safe inside a class and don’t let anyone access it direct
🔹 2. We use private variables to protect data.

Private means no one can access the variable directly from outside the class

🔹 3. We use public methods to access or change the data.

These methods are called getters and setters.

🔹 4. Encapsulation makes the program secure and easy to manage

public class Student {
private String name;
private int age;

// Getter method for name
public String getName() {
    return name;
}

// Setter method for name
public void setName(String name) {
    this.name = name;
}

// Getter method for age
public int getAge() {
    return age;
}

// Setter method for age
public void setAge(int age) {
    if (age > 0) {
        this.age = age;
    }
}

}
example, ::
1)the Student class has private fields name and age.
2)Public getter and setter methods are provided to access and modify these fields.
3)The setter for age includes a basic validation check.
