All Implemented Interfaces:

Serializable

public class EmptyNameException
extends Exception

Checked exception thrown when an attempt is made to create or update an entity that requires a non-empty name (full name, category name, product name, etc.) but the provided name is null, empty, or consists only of whitespace.

The name field is mandatory in many domain entities:

• User and its subclasses (Customer, Admin) – full name
• Category – category title
• Product – product title
• CreditCard – cardholder name

Empty names would violate data integrity, search functionality, and user experience.

Typical scenarios that trigger this exception:

• User registration or profile update with blank full name
• Creating a category/product without entering a name
• Adding a credit card with missing cardholder name
• Admin tools or data import processes submitting records with empty names

This is a checked exception, forcing the caller to handle the missing name explicitly. It represents an expected, recoverable validation error in normal application flow.
