Java: Decorator Pattern
Answer
It allows adding features without altering existing code.
The Decorator pattern provides a way to extend functionality without changing the original class, adhering to the Open/Closed Principle. This is beneficial in scenarios where modifications to existing code could introduce bugs or are impractical due to the code's widespread use. For example, adding a gift wrap feature to an order can be done without changing the Order class directly.
