Understanding the Decorator Design Pattern in Java
The Decorator Design Pattern is a structural design pattern that allows behavior to be added to individual objects dynamically without affecting other objects from the same class. It works by wrapping the original object inside special wrapper objects that add the new behavior. This approach is especially useful when there are many possible combinations of behaviors, and subclassing for each variation is not feasible. What is the Decorator Design Pattern? Decorator pattern lets you attach additional responsibilities to an object at runtime. Instead of creating many subclasses for every possible combination, decorators allow behaviors to be composed automatically in a flexible and reusable way. Real-World Analogy: Pizza Toppings Think about ordering a pizza. You start with a base pizza and then add various toppings like extra cheese, jalapenos, mushrooms, etc. Instead of creating a subclass for every topping combination, each topping acts as a decorator that wraps the pizza, ...
