    Proxy design pattern can be used in a wide variety of scenario in

    Java. Some of these are as follows:

    1. Virtual Proxy: This is a virtual object that acts as a proxy

    for objects that are very expensive to create. It is used in

    Lazy Loading. When client makes the first request, the real

    object is created.

    2. Remote Proxy: This is a local object that provides access

    to a remote object. It is generally used in Remote Method

    Invocation (RMI) and Remote Procedure Call (RPC). It is

    also known as a Stub.

    3. Protective Proxy: This is an object that control the access

    to a Master object. It can authenticate and authorize the

    client for accessing the Master object. If client has right

    permissions, it allows client to access the main object.

    4. Smart Proxy: It is an object that can add additional

    information to the main object. It can track the number of

    other objects accessing the main object. It can track the

    different clients from where request is coming. It can even

    deny access to an object if the number of requests is

    greater than a threshold.
