Creating action in Object Orientated Programming

I just started an Object Orientated Programming class. I'm trying to write a program that adds a Customer to a System by giving name and age parameters, but duplicates are not allowed.

If I were writing this Java code normally, I would simply create a class named Customer with name and age instance variables with a method called new() which would create a new customer.

But since this isn't a list or anything, instead simply adding a Customer to a System, where do I write the method to not allow duplicates?

Create field in System or make System extend Set and override equals() function in Customer class to compare fields that can't be duplicates.
