• Car interface
  
• SportCar that extends Car
  

interface Car{
}

interface SportCar extends Car{
}


class DefaultCar implements Car {
}

@FerrariQualifier
class DefaultSportCar implements SportCar {
}

What I would like to inject:

@Inject
private Car car; //inject DefaultCar

@Inject
@FerrariQualifier
private Car ferrari; //inject DefaultSportCar


@Inject
private SportCar sportCar;//inject DefaultSportCar
