Inject an array of Objects in Guice

Question

I would like to achieve something similar to the following in Guice:

public MyClass {

    private final InjectedObject[] injectedObjects;

    @Inject
    public MyClass(InjectedObject[] injectedObjects) {
        this.injectedObjects=injectedObjects;
    }
}

ie I would like to be able to create a certain number of instances of an object, and inject them into another object as an array. I could probably do this instead:

public MyClass {

    private final InjectedObject[] injectedObjects;

    @Inject
    public MyClass(InjectedObjectProvider injectedObjectProvider) {
        this.injectedObjects=injectedObjectProvider.getArrayOfInjectedObjects(5);
    }
}

...but I was wondering if there was another route that was more elegant?

Not sure if this suits your needs, but Multibindings worked for me when I needed to inject multiple elements of the same kind (it produces a set though).
