Quizplus · Accepted Answer

The adapter pattern is specifically designed to integrate new functionality with an existing system without modifying the existing code. This is done by creating an adapter class that adapts the new functionality to the existing system's interface. Therefore, using the adapter pattern is the best choice for integrating a new function into an existing system.
