The Decorator Pattern is a design pattern that dynamically adds some additional functionality to an object. It is more flexible than generating subclasses. This pattern creates a decorator class to wrap the original class and provides additional functionality while maintaining the integrity of the original class’s functionality.
An example is given to illustrate how to use the Decorator Pattern. Suppose we have a simple text printing functionality, and now we need to add different decorations to the printing functionality, such as bold, italics, or color, without changing the original printing class.
