// A simple dependency class
public class Dependency {
    public void performAction() {
        System.out.println("Action performed by Dependency");
    }
}

// Service class without dependency injection
public class MyService {
    private final Dependency dependency;

    // Constructor creating an instance of Dependency internally
    public MyService() {
        this.dependency = new Dependency();
    }

    public void doSomething() {
        // Using the internally created dependency
        dependency.performAction();
    }
}

// Main application class
public class MyApp {
    public static void main(String[] args) {
        // Creating an instance of MyService
        MyService myService = new MyService();

        // Using the MyService instance
        myService.doSomething();
