What is the Null Object Pattern in programming?

The Null Object Pattern is a design pattern that uses a special object to represent a null value, avoiding null checks.

Can you give me an example of how to implement it?

Sure! Instead of returning null, you return an instance of a class that implements the same interface but does nothing.

What are the benefits of using this pattern?

It helps to reduce null checks, simplifies code, and can improve readability and maintainability.

Are there any drawbacks to using the Null Object Pattern?

Yes, it can lead to confusion if the null object behaves unexpectedly or if it's not clear that it's a placeholder.
