Adapter pattern provides a different interface to an object. But the

Proxy always provides same interface to the object.

Adapter is like providing an interface suitable to client’s use. But

Proxy is same interface that has additional feature or check.

E.g. In electrical appliances we use Adapter to convert from one

type of socket to another type of socket. In case of proxy, we have a

plug with built-in surge protector. The interface for plug and the

original device remains same.
