I just discovered that you can explicitly use the word "constructor" when defining a class; and that is mandatory only when specifying a visibility modifier for the constructor, or when using an annotation.

If you use dependency injection framework like Dagger you can use @Inject annotation for constructor to mark that this constructor is injectable.
