Software Design Patterns Questions
The Decorator design pattern is a structural design pattern that allows adding new functionality to an existing object dynamically without altering its structure. It involves creating a decorator class that wraps the original object and provides additional behavior by adding new methods or modifying existing ones. This pattern follows the open-closed principle, as it allows extending the functionality of an object without modifying its code. The decorator class implements the same interface as the original object, allowing it to be used interchangeably. This pattern promotes code reusability and flexibility, as decorators can be stacked or combined to add multiple functionalities to an object.
