Stamp Coupling Improvement

Question

I study programming in my college Stamp Coupling. We are learning system analysis and design. My classmate ask me the question, how to solve Stamp Coupling? I ask Teacher who said "Use an interface to limit access from clients", but I still misunderstand.

This is way too broad to answer. You'll have to tell us the specific case in which you have to solve stamp coupling (preferably with relevant code). — Eran, Dec 14 '17 at 09:54

Well, since the print method needs only the name, address and billing info of the Customer, you don't have to pass anything else to it.

You can define an interface:

public interface PrintableCustomer
{
    public ... getName();
    public ... getAddress();
    public ... getBillingInfo();
}

Now, let the Customer class implement PrintableCustomer.

The print method can now accept a PrintableCustomer instead of a Customer.

void print (PrintableCustomer customer)
{
    ...
}

Now print() only sees the properties that it needs.
