Answer 1

One use would be if you were using the provides directive:

module superman {
    provides com.github.me.superhero.Superhero with com.github.me.superhero.Batman;
    provides com.github.me.superhero.Superhero with com.github.me.superhero.IronMan;
}

Using an import would look like:

import com.github.me.superhero.*;

module superman {
    provides Superhero with Batman;
    provides Superhero with IronMan;
}
