Solution: Hidden Server Configuration

Explore how private member inner classes in Java enable hidden server configuration. Learn to encapsulate logic tightly within outer classes, allowing secure access to class members and improving overall design.

We'll cover the following...
Java 25
public class Server {
    // 1. Private Inner Class
    private class Config {
        int port = 8080;
    }
    public void start() {
        // 2. Instantiate Inner Class
        Config config = new Config();
        // 3. Access internal details
        System.out.println("Server started on port: " + config.port);
    }
    public static void main(String[] args) {
        Server server = new Server();
        server.start();
    }
}
