  1. Dependency Injection:

  2. Important Words:

    • Decoupling, dependencies, inversion of control, testability, maintainability.

  3. Example Code:

public class Client {
    private Service service;

    public Client(Service service) {
        this.service = service;
    }

    public void doSomething() {
        service.execute();
    }
}

public interface Service {
    void execute();
}

public class DependencyInjectionExample {
    public static void main(String[] args) {
        Service service = new ServiceImpl();
        Client client = new Client(service);
        client.doSomething();
    }
}
