Null Object Design Pattern

The Null Object Design Pattern provides a default object that behaves like a real object but signifies the absence of a real object or value. Instead of checking for null or missing data, the code can interact with this "null" object safely, knowing it will respond appropriately without causing errors. This approach simplifies code logic and handling missing cases, making systems more robust and easier to maintain. Think of it as a placeholder that guarantees consistent behavior, eliminating the need for repetitive null checks everywhere in the code.
