None (software design pattern)

The Null Object pattern is a software design approach where a special object represents the absence of a real object, instead of using null or nothing. This "null" object responds to method calls in a predictable way, avoiding errors or extra checks in the code. It simplifies handling situations where an object might be missing, making programs more robust and easier to read. For example, instead of checking if a user exists before doing something, a Null Object can stand in for "no user" and safely handle the request.
