Can Someone Please explain a bit about Messages 101 in OOP Bootcamp

Hi! can anyone please explain in brief about how objects communicate in this cahpter ( https://www.laracasts.com/series/object-oriented-bootcamp-in-php/episodes/5?autoplay=true ). I tried many time but still getting confused in it.

Few things like:

class Business { public function hire ( Person $person) {

}

theses things like why you write Person in the function like that.

Thanks

It's called dependency injection in PHP. In a nutshell, it's like calling a class without instantiation.
