Java: Proxy and Adapter
Answer
Proxy mimics the real object's interface. Frame the concept in practical terms so you can explain it during interview discussion.
To ensure clients use a Proxy without knowing it's a stand-in, the Proxy must implement the same interface as the real object. In a database-heavy system, a Proxy can cache results to reduce database access. The client interacts with the Proxy as if it's the actual database object.
