Guice Beginner - How to bind concrete classes?

Question

I have this class:

public class House {
    private final Door door;
    private final Window window;
    private final Roof roof;

    @Inject
    public House(         


        

Answer 1

Guice's Just-In-Time binding does exactly what you want. Given your Door, Window and Roof meet following requirements (quoted from the Guice documentation):

either a public, no-arguments constructor, or a constructor with the @Inject annotation

an empty Module implementation will be sufficient:

public class HouseModule extends AbstractModule {
    @Override
    protected void configure() {
    }
}
