This pattern is often used when dealing with frameworks, libraries, and APIs to easily "adapt" the old and existing interfaces to the new requirements of a program.
The adapter pattern converts the interface of another existing class into an interface waited by the existing clients to allow them to work together. Thanks to this pattern, you can integrate components for which you normally cannot modify the source code and things that often appear with the use of a framework.
Note that you should avoid using this pattern if you already have source code access to the component.
