12. Encapsulation: Access Modifiers in Action

Scenario

How do access modifiers (private, protected, public) affect what is inherited and accessible in a subclass?

Code Block

package hospital;

class Employee {
    public String name = "Global";
    protected double salary = 50000;
    private String healthID = "HID-123";
    int vacationDays = 20; // Default (Package-private)
}

class Doctor extends Employee {
    void printDetails() {
        System.out.println("Name: " + name);      // Accessible (public)
        System.out.println("Salary: " + salary);  // Accessible (protected)
        // System.out.println(healthID);          // ERROR: private
        System.out.println("Days: " + vacationDays); // Accessible (same package)
    }
}

public class Main {
    public static void main(String[] args) {
        new Doctor().printDetails();
    }
}
