Framework based DI Code Example

I highly discourage anybody from using hard coded strings in-line. The example in the last section of the page would be better if we added an static class to it that contains the strings:

//static class provided by the framework or written by the user to indicate which dependencies are available
public static class MyAvailableServices{
    public static final string CarBuilderService = "CarBuilderService";
    public static final string VanBuilderService = "VanBuilderService";
}

public class MyApplication {
    public static void main(String[] args) {
        Service service = (Service)DependencyManager.get(MyAvailableServices.CarBuilderService);
        Car car = (Car)service.getService(Car.class);
        car.setPedalPressure(5);
        float speed = car.getSpeedInMPH();
    }
}

Registry Pattern

Should not this article reference the Registry Pattern which was very prevalent until IoC/DI was popularised?

Inline external links

Is it correct to put inline links to external sites in the article? See links to CDI, Weld, Salta & Dagger in

It is just "configuration" not more :-)

For me the term "Dependency injection" and the corresponding Wikipedia article are way too complicated.

For me it just "Configuration". But some people don't like it simple, they prefer bloated theory.
