Where to put objects and methods
I want to make a plan for example to the grocery store, and I open 2 classes one for product ,and the other for customers,
A.Where should I put the object(the customers and the products)? in the main? in their class?
B. Where should I put the methods like buy?
(I started to learn programming a month ago, so if possible a basic answer (not deep ..))
Re: Where to put objects and methods
The way to think about something like this is to model the real world. Customers buy products from stores. So one possibility is have a grocery store class return an instance of whatever product is being bought by the customer.

Re: Where to put objects and methods
a class defines the needed information. The class is the blueprint. All classes create objects, and all objects contain characteristics.
Re: Where to put objects and methods
Not quite. Some classes cannot be instantiated and therefore don't create objects. One such example is the java.lang.Math class which contains only static methods. And as such, it does not have any inherent characteristics that an instantiable class might have.Originally Posted by arminius
