Design mode (proxy mode)

The proxy mode is an object that proxies other objects and provides functionality externally, as in the following example Proxyfuncimpl Agent Funcimpl provides functionality externally.

• Func

 Public Interface Func {    publicvoid  doAction ();}

• Funcimpl

 Public class Implements Func {    @Override    publicvoid  doAction () {        System.out.println ( "Funcimpl");}    }

• Proxyfuncimpl

 Public class Implements Func {        private  Func func;        Proxyfuncimpl () {        new  Funcimpl ();    }        @Override    publicvoid  doAction () {        System.out.println (" Proxyfuncimpl ");        Func.doaction ();    }}

• APP Test class

 Public class App {    publicstaticvoid  main (string[] args) {        new Proxyfuncimpl ();        Proxy.doaction ();    }}
