i am making a program which has a super class called Building, this class has one variable which is the address of the building. Then i have two sub-classes one is called Apartment the other one is called Restaurant.
I defined those classes like this:
public class Apartment extends Building;
public class Restaurant extends Building;
Now i have a function public void register(Building build);
and i want to know how can i choose a sub-class to store the information by receiving the super class only.
E.g:
0.Apartment
1.Restaurant
Which building do you have?
Now depending on user's answer i will ask
How many rooms, bathrooms, etc.
My starter point is Building class now i need to choose, if the user answered 0 i will be using Apartment sub-class, otherwise i will use Restaurant sub-class.
How can i do this?
Let me know if there is a better way to do this.
Thank you.
You could go with method overloading: Make register methods with your sub-classes as arguments. Do the sub-class specific work in those methods and then call a private register(Building building) method to do the common work.
