Is Having an Instance of a Class Inside Another Class Considered a Bad Practice?
So, basically what I'm trying to say is to imagine that you are working on a project that is a hotel reservation system.
So you have the HotelMenu class which will show the options for the Hotel at which you are trying to stay. Inside the HotelMenu, there will a field of type Hotel, which contains all the methods that you could do for a Hotel, such as makeReservation(), cancelReservation(), seeRoomsAvailable(), and so on.
At the same time, inside the Hotel class, there would be an instance variable of type Room, which would contain the room characteristics such as bedSize, for example.
Would the above program be a bad programming practice. I thought so because if you were to make a change in the Room class, then it would break all the other classes. Like let's say that you are modifying the Room class to add a method to change the bedSize, and this would in turn affect the Hotel class, which would ultimately affect the HotelMenu, breaking the whole system. Therefore, would this be an example of bad programming practice due to tight coupling?
