Summary
The Proxy Pattern provides an intermediary that acts as an interface to another resource, while the Adapter Pattern is used to connect two incompatible interfaces that otherwise cannot be connected directly. The Proxy Pattern is also similar to the Adapter and Decorator, but its purpose is to control access of objects, preventing clients to directly access objects, instead, it acts as a real object and can provide alternate behavior or forward request to the original object.

Summary
This article discusses the three types of Structural Design Patterns in Java: Creational, Structural, and Behavioral. The Proxy Pattern provides an intermediary that acts as an interface to another resource, while the Decorator Pattern enhances the behavior of an object. The Adapter Pattern is used to connect two incompatible interfaces that otherwise cannot be connected directly, while the Bridge Pattern decouples an abstraction from its implementation so that the two can vary independently.

Summary
The proxy pattern is also quite similar to the Adapter and Decorator, but its purpose is to control access of objects.
Proxy prevents clients to directly access objects, instead, it acts as a real object and can provide alternate behavior or forward request to the original object.

Proxy Design Pattern - GeeksforGeeks
geeksforgeeks.org
In computer programming, the proxy pattern is a software design pattern. A proxy, in its most general form, is a class functioning as an interface to something else. The proxy could interface to anything: a network connection, a large object in memory, a file, or some other resource that is expensive or impossible to duplicate. In short, a proxy is a wrapper or agent object that is being called by the client to access the real serving object behind the scenes. Use of the proxy can simply be forwarding to the real object, or can provide additional logic. In the proxy, extra functionality can be provided, for example caching when operations on the real object are resource intensive, or checking preconditions before operations on the real object are invoked. For the client, usage of a proxy object is similar to using the real object, because both implement the same interface.
