Adapter pattern example consider a scenario in which there is an app that s developed in the us which returns the top speed of luxury cars in miles per hour mph.

Adapter design patterns in java howtodoinjava. Wikipedia says in software engineering the adapter pattern is a software design pattern that allows the interface of an existing class to be used as another interface. In other words to provide the interface according to client requirement while using the services of a class with a different interface. The definition of adapter provided in the original gang of four book on design patterns states. The adapter acts as a wrapper between two objects.
